Question

Complete factoring by writing polynomial as the product of two factors. 10a2−20a

=10a
( ______ )

Answer 1

(a-2)

Explanation:

I think that your original expression was

10
`a^(2)` - 20a

There are 2 terms. The first term is 10
`a^(2)` and the second term is 20a. What factors do they have in common? 10a, so that is what is pulled out. What do we have to multiply 10a by to get our original equation?

We would multiply 10a by a to get 10
`a^(2)`.

We would multiply 10a by 2 to get 20a.

10a(a - 2)
