The Factor Theorem
Introduction
Hopefully an easy ride. Started off with a quadratic equation
x² - 8x - 20 = 0
This works out to
(x + 10)(x -2) = 0
So (x + 10) and (x -2) are factors and we can see either x = -10 and x = 2 are known as solutions. The take away was given we know solution we can reverse engineer factors. So if x = 2 is a solution, (x -2) is a factor
