Question

Completely factor 4x2 + 12x + 8.
4(x + _)(x + _ )
Can someone explain to me Step by Step, Please!

Answer 1

Using the GCF

Answer 2

common factor of 4,12 and 8 is 4 since 4 goes in to each evenly
you can start with
\[4(x^2+3x+2)\]

Answer 3

I would divide through this equation by my leading coefficient which is 4 so we are left with x^2+3x+2. Now we need to see what numbers times each other =2 and added together equal 3. 2x1=2 and 2+1=3 so it looks like we found this one pretty easily. Our answer would be (x+2)(X+1)

Answer 4

Thanks guys! @satellite73 and @robert2
