Question

Factor:
2y^4-6y^3-8y^2

Answer 1

Do you see any factors that you can bring out front? Factors that are common to 2y^4, -6y^3 and -8y^2 ?

Answer 2

yeah 2y?

Answer 3

2 (y-4) y^2 (y+1)

Answer 4

I agree, 2y can be brought out. What does it look like factored with 2y in the front ?

Answer 5

Factoring out \(2y\) leaves you with \((2y)(y^3-3y^2-4y)\).
It can still be factored more.

Answer 6

okay how do you factor further?

Answer 7

Perhaps another y can be factored? This would leave 2y^2 in the front
