You can put this solution on YOUR website!
You can only add and subtract like terms. Like terms have the same exact variables (letters) and the same exact exponents (powers).
3x%5E2%2B4x%2B3x%5E2-4y
3x%5E2%2B3x%5E2%2B4x-4y
%283%2B3%29x%5E2%2B4x-4y
6x%5E2%2B4x-4y That's all you can do.
:
%285x-2y%29-%284x%2B8y%29
5x-2y-4x-8y
5x-4x-2y-8y
%285-4%29x%2B%28-2-8%29y
1x-10y
x-10y That's all you can do.
:
You can multiply and divide unlike terms
3x%5E3%282x%5E2%29
3%2A2%2Ax%5E3%2Ax%5E2
(NOTE: x%5E3=x%2Ax%2Ax and x%5E2=x%2Ax so x%5E3%2Ax%5E2=x%2Ax%2Ax%2Ax%2Ax=x%5E5)
highlight%286x%5E5%29
Happy Calculating!!!
