Hi, I'm Ryan Ault, I'm a physicist, and this is how to do polynomial factoring. If we have a polynomial, which can be x-squared plus x minus six, we can find the factors of this by simply following a mechanism where you write the negative six on the top, and you write a one on the bottom. So what we need to do is find two numbers that multiply to give you negative six, and that add together to give you one. So we could try three and negative two, and we see that three times negative two is negative six, and that three plus negative two is just one, so these numbers work. And what these numbers are, are the numbers for x that allow it to be zero. So we could write the factors now as x plus three, times x minus two, is equal to zero. I'm Ryan Ault, and this is how to do polynomial factoring.
