For this exercise you need to remember:
1) The mulitplication of signs:
2) By definition, like terms contain the same variables with the same exponent.
Then knowing this, and given the equations:
and
You must subtract the like terms, which means that you must subtract the numerical coefficients of each term.
Then, you get the result is:
We can divide each term by a factor of .
You don't need a coefficient of , so simplify that.
