Question

How would I solve this:

Answer 1

(x+3)-2(3x+9)=2(x+3)(3x+9)

Answer 2

(x+3)-2(3(x+3))=2(x+3)(3(x+3))
(1-6)(x+3)=6(x+3)^2
-5(x+3)=6(x+3)^2
Let x+3=y
6y^2+5y=0
y(6y+5)=0
y =0, 6y+5=0

Answer 3

but what is x equal to

Answer 4

okay, can you write 3x+9 as 3(x+3)? You can right?

So you equation changes to:

can you proceed now?
