In a previous article, we covered using Factoring to solve and equation. We went through our equation step-by-step and then went back to check our answer. However, we also noted that Factoring...

In fields such as chemistry and aerodynamics, the relationship between pressure, temperature and volume is defined by the equation of state for an ideal gas. The equation states that the pressure...

To solve for quadratic inequalities, use the quadratic formula to solve for X, and plug X back into the inequalities to make the inequality true. Get an example of a quadratic inequality equation...

Determine the degree of a polynomial by calculating the highest value of an exponent in the equation. Solve a polynomial equation for the degree of the polynomial with help from a tutor in this...

Solving mathematical equations is a part of everyday life. If the proper order of solving an arithmetic problem is followed, a correct answer is the result. The order is easy to remember if you...

The domain of a function is all the values of the control variable, or the x value, for which the function is defined. The range of a function is all the values of the dependent variable, or the y...

Polynomials are different from many other kinds of equations because they have multiple solutions. A polynomial can have two, three, or even more different solutions. If you know how to factor...

A lens, an arch and a cross-section of a dome or satellite dish are all examples of parabolas. They have many uses in astronomy, physics and architecture.Algebraically, a parabola is the U-shaped...

The slope--or slant--of a line can be quantified. You are probably used to referring to inclines as “steep” or “gradual,” but it is possible to give a numerical value...

A trinomial expression is any polynomial expression which has exactly three terms. In most cases, "solving" means factoring the expression out into its simplest components. Usually, your trinomial...

Factoring is one of the ways to break down a trinomial, or a math problem with three unlike terms, by utilizing the factors of each term of the trinomial. Once a trinomial has been factored, it is...

There are three basic steps to factoring cubes. First, factor out any common terms in the cubic function. Then, look for a differences or sum of cubes and factor it. At this point, if the problem...

Solving polynomials is one of the most fundamental skills in algebra. Many other skills that you will face in the algebra classroom stem from this basic skill, so you must master it if you are...

Solving linear equations is one of the most fundamental skills an algebra student can master. Most algebraic equations require the skills used when solving linear equations. This fact makes it...

Let me guide you through one of the many types of mathematical problems that you are likely to encounter sometime during your high school math career--how to find the distance between two points...

Mathematics is one of those most dreaded subjects for many students throughout their school years. With graphs, complex equations, and the many different shapes that can be involved it is no...

A radian is the measurement of the angle created when you wrap the radius of a circle around its circumference. Sometimes when you solve a trigonometry problem involving the measurement of angle,...

Graphing any kind of equation can be time consuming, which is probably why graphing calculators quickly become a math student's best friend. Calculators can do almost any kind of math problem for...

Geometry can be one of the most confusing years of math that you will encounter in high school. With all the different shapes, types of angles and formulas to remember you may start to feel that...

Geometry can be one of the most confusing years of math that you will encounter in high school. With all the different shapes, types of angles and formulas to remember you may start to feel that...

In math, word problems refer to exercises that provide the reader with background information or a story. Knowing how to solve word problems is a good skill for students to have because problems...

Don't let absolute value symbols in an inequality have you throwing your hands up in the air in frustration. This article will guide you through how to solve absolute value inequalities without...

Algebra is challenging for many students. Multiplying binomials can be confusing until you understand how the distributive method of multiplying works. However, the FOIL method is a little trick...

Double inequalities may appear too intimidating at first to solve because there are three sides to the equation, but, if you follow the step-by-step guide that provided below you may find them a...

One of the most fundamental concepts that you need to learn in chemistry is how to write a chemical equation. Chemical equations are used whenever a compound is formed or decomposed. This is why...

When you solve a quadratic equation the solutions will be either real numbers or imaginary numbers. You can determine what kind of solutions the equation will have without actually having to solve...

Solving proportion problems are some of the math problems that frequently cause problems for students. If you need help solving proportion math problems then here are some tips to help get you on...

Quadratic equations are those that can be stated as: y = ax^2 + bx + c, where x is the variable, a, b, and c are constants, and the constant a is not 0. Graphically, quadratic equations are...

"Solve the quadratic equation ax² + bx + c = 0, for the value of x." These words have flummoxed many beginning math students, but this task is not nearly as intimidating as it appears. To...

A two dimensional Cartesian graph shows how two quantities, called variables, relate to one another. It is formed by a horizontal axis (typically called the x-axis) and a vertical axis (the...

Addition does not have to be a difficult concept to teach. It can be made fun if taught to age appropriate children or those who seem interested or ready. Addition like everything else that you...
