Question

How do you factor `x^3y^2+xy`?

Answer 1

`xy(x^2y +1)`

Explanation:

Always look for a common factor first.
In this case both terns have `xy`

`x^3y^2 + xy`

=`xy(x^2y +1)`

Take note that anything divided by itself equals 1.

The second term of 1 must appear in the bracket. If it is left out, when we multiply out we will not get back to the original expression.
