Question

How do you factor `16x^2 y^2 +8xy^2 -20xy`?

Answer 1

`4xy(4xy + 2y -5)`

Explanation:

To factor `16x^2y^2 + 8xy^2 - 20xy`
begin with the greatest factor common to each term
for this expression the GCF (greatest common factor) is
`4xy`

This can be placed outside of the parenthesis to determine the
associate factors to complete the factoring.

`4xy(4xy) = 16x^2y^2`
`4xy(2y) = 8xy^2`
`4xy(5) = 20xy`

Making the factors
`4xy(4xy + 2y -5)`
