3x^2+20x+12
if that ^ represnts the area of a rectangle, find two binomials that can represent its dimensions

3x^2+20x+12
x^2+20x+36
(3x+_a_)(3x+_b_)
What times wat =20 is a
and adds up to 36 is b
Then divide a by 3 and b by 3
giving u:
(x+__)(x+__)
then make x = to 0
x+__=0 x+__=0
subtract over the number and you will have your answer
