# How do you factor quadratic equations with a coefficient?

##### 1 Answer

Good question .

basically what are asking me to factor is :

here is an eg.

First you need to make column like this

SUM = COEFFICIENT OF x =( -15)

product = (COEFFICIENT of x^2

Now you have to find factors which have a sum of -15 and a product of 36

THE FACTORS ARE (-12), (-3)

So now what we do is split the middle term in the equation and factor it out
