5ab  -   10a^2b

Take  out the greatest   common  factor  =  5ab

To  find out what goes into  the  parentheses......just divide  the original terms by this GCF

5ab                 10a^2 b

___    -           _______   =         1  - 2a

5ab                   5ab

So we have

5ab  ( 1  - 2a  )

5ab - 10a^2b

That is our equation

We can notice that 5ab is a factor of both numbers. So we take it as common

(5ab / 5ab) (10a^2b / 5ab) = 5ab (1-2a)

Hope that helps!!! :)

1. We first, just multiply it out (5ab x 1) - (5ab x 2a)

2. 5ab - 10a²b

3. We have a common factor b, b(5a - 10a²)

4. We factor again b(a(5-10a)

5. We factor again b(a(5(1-2a))

We get 5ab(1-2a))

Please tell me if you have any questions.

you guys are so hecking fast its amazing! Okay so i think where i was struggling is the fact that 2a-1 was just being flipped for simplicity. i think i get it now so thanks yall!
