You can put this solution on YOUR website! Example 1: Simplify by combining like terms.
Are there any like terms that we can combine?
It looks like it. Both terms have the same variable part, a.
7a-10a
(7-10)a
-3a
Simplify 5x^2+7x-2x^2-10x+5
It looks like we have two terms that have an x squared that we can combine and we have two terms that have an x that we can combine. The poor 5 does not have anything it can combine with so it will have to stay 5.
Grouping like terms together and combining them we get:
5x^2+7x-2x^2-10x+5
5x^2-2x^2+7-10x+5
3x^2-3x+5
