Question

Factoring : 4y^2-8y-2xy

Answer 1

first find common factor of 3 terms
(the GCF)
GCF of 4,8 and 2 = 2
GCF of y^2, y and xy is y

so out gcf is 2y

can you continue?

Answer 2

Yes. I will post my answer later on here, mind checking it then?

Answer 3

no problem

Answer 4

I got 4y^2-8y-2xy!

Answer 5

thats the original expression

you asked to factorize it :

GCF = 2y
now you need to divide each term by the GCF

4y^2 / 2y = 2y
-8y / 2y = -4
-2xy / 2y = ?

can you do the last one?

Answer 6

No, I know. I copied the wrong one! LOL, my bad! So silly of me, but that is what I got. :)

Answer 7

Mind helping me with some others?

Answer 8

you sure you can finish this one?
need more help?

Answer 9

I got 2y(2y-4-x)

Answer 10

yea

Answer 11

ok

Answer 12

2ax+2bx-3a-3b, how would I start off on that one?

Answer 13

here there is no common factor of all the terms
so try grouping:

2ax + 2bx - 3a - 3b
= 2x(a + b) - 3(a + b)

(a - b) is a common factor:, so

its (2x - 3)(a + b)

Answer 14

* (a + b) is a common factor

Answer 15

Okay, thanks. I am going to try to do a few of my own and then have you check them? :)

Answer 16

thats the way to go

Answer 17

Can you help me with C^3-27?
