Solving by Factoring
Solve the polynomial equation using factoring and the Zero Product Property.
Step 1 — Write in standard form. Subtract from both sides so that one side equals zero. Rearrange in descending order:
Step 2 — Factor the greatest common factor. All terms share a common factor of . Factor it out:
Step 3 — Factor the trinomial. The resulting trinomial is a perfect square trinomial:
Step 4 — Apply the Zero Product Property. Set each variable factor equal to zero:
Step 5 — Solve each equation:
The distinct solutions are and .
