Following steps are use to simplify and solve the polynomial expression

1) Write the equation in the correct form. To be in the correct form, you
must remove all parentheses from each side of the equation by
distributing, combine all like terms, and finally set the equation equal
to zero with the terms written in descending order.

2) Use a factoring strategies to factor the problem.

3) Use the Zero Product Property and set each factor containing a variable equal to zero.

4) Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
