Solving
Solve by first expanding the left side and moving the constant to the left to reach standard form.
Multiply the binomials (which form a difference of squares): . Subtract from both sides to write the equation in standard form: . Factor the resulting difference of squares: . Use the Zero Product Property to set each factor to zero: or . Solve for the variable to find the solutions: and .
