Question 257291: This is kind of new for me to complete this type of problem, so I need some
help.

Factoring : Finding GCF/Reverse FOIL (Quadratic - 2 binomials)

8y^3 + 2y - 4y^2
Okay, this is my thinking.
I know that 2 is the greatest common factor.
I also know that y is in all three, but the lowest is just y^1, so
my greatest common factor is going to be 2y
I don't know how to explain this, but I'll try:
2y ( 4y^2 + 1 - 2y)
I put the greatest common factor on the outer parenthesis. Then
I figured out what numbers I need to reach to know what numbers I would
have to put inside the parenthesis.
This is a little confusing for me. Please help me if you can.

8y%5E3+%2B+2y+-+4y%5E2 Start with the given expression.


2y%284y%5E2%2B1-2y%29 Factor out the GCF 2y


------------------------------------------------------------


Answer:
So 8y%5E3%2B2y-4y%5E2 simply factors to 2y%284y%5E2%2B1-2y%29 since 4y%5E2%2B1-2y can't be factored further.
