How do you factor quadratic equations with a coefficient?
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
