How do you simplify #4x^2y + 8xy^2 - 9x^2y - 4xy^2 + 15 x^2y#?
Combine like terms, then find what is common amongst what's left and you'll get to
To simplify this expression, we look for the common terms and simplify them first:
There are some terms that are
Now we can see that the
Now we can find common factors in these two terms and factor them out (I see 2xy):
