How to factor a quadratic
Steps to find the root of a quadratic equation: By applying the values in the formula: x = − x ± b 2 − 4 a c 2 a There are few conditions to adhere to: There is one real root while b2 - 4ac = 0 is
So if we were to factor this, this would be equal to x plus 5, times x plus 10. And multiply it out. I encourage you to multiply this out, and see that this is indeed x squared plus 15x, plus 10. In fact, let's do it. x
