SOLUTION: Please help me! I need to know what an equivalent expression of this would be -m(2m+2n)+3mn+2m^2 (to the second power at the end in case my use of keys may be wrong!) Thanks!!

-m%282m%2B2n%29%2B3mn%2B2m%5E2+
=-m%2A2m-m%2A2n%2B3mn%2B2m%5E2+
=-2m%5E2-2mn%2B3mn%2B2m%5E2+
=-cross%282m%5E2%29-2mn%2B3mn%2Bcross%282m%5E2%29+
=-2mn%2B3mn+
=mn+

so, expression -m%282m%2B2n%29%2B3mn%2B2m%5E2+ is equivalent to expression mn+
