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 - 10a^{2}b

3. We have a common factor b, b(5a - 10a^{2})

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.
