Solve Quadratic Equations by FactoringTo find the solutions of a quadratic equation ax2 + bx + c = 0, factor the left side and use the Zero Product Property.
ZPP Zero Product Property If AB = 0 then A = 0 or B = 0.
Set each of the factors equal to zero and solve for x in each equation.
Examples: Factor the quadratic equations and use the ZPP to find the solutions of the equation.
