Question

Factor the expression
40y^3-8y^2

Answer 1

you can use quadratic formula here if you know how to use the method

Answer 2

Nope im just trying to understand the basic way of factoring this expression and getting the correct answer I think quad is the last part of my term

Answer 3

This is a tricky one. First pull the number that both sets are divisible by. So 8. Then you have to pull a like y term. So y^2.
So it becomes something like 8y^2(5y-1)

Answer 4

thank you ill keep working at it

Answer 5

It just takes a WHOLE lot of practice. Factor problems until your hand falls off and then something will magically click. That's what I did and now I can factor pretty much any problem

Answer 6

ok sounds good

Answer 7

The first step will be to look for coefficients and exponents which divide all terms. In this case both terms are even, for example, and have expressions with y in them.
