Simplify the expression below (3xsquaredy-5xy+12xysquared) - (5xysquared + 4xy)

Okay, so lets do this!

(3x^2y - 5xy + 12xy^2) - (5xy^2 + 4xy)

Simplify the sum and then order the factors of 3x^2y.

Now order factors for - 5xy to get (3yx^2 + 12xy^2 - 5yx) - (5xy^2 + 4yx)

Order the factors for 4xy to get 3yx^2 + 12xy^2 - 5yx + - 5xy^2 - 4yx

Reorder the terms:

3yx^2 + 12xy^2 - 5xy^2 - 5yx - 4yx. Our answer.
