Solve for x. x + 6 = √(12 + x) (x + 6)(x + 6) = 12 + x {squared both sides to get rid of square root sign} x² + 12x + 36 = 12 + x {used foil method} x² + 11x + 24 = 0 {subtracted 12 and subtracted x from both sides} (x + 8)(x + 3) = 0 {factored into two binomials} x + 8 = 0 or x + 3 = 0 {set each factor equal to 0} x = - 8 or x = - 3 {solved each equation for x} © Algebra House
