A:

Answer:Josh's solution is NOT correct.Step-by-step explanation:Josh's solution is NOT correct.x^2 - 6x - 7 = 0As you know:-7 = (-7) * (+1) and -6 = (-7) + (+1) = -6So factor x^2 - 6x - 7 = 0, you have(x - 7)(x + 1) = 0Set each factor = 0 to solve the equationx - 7 = 0; x = 7x + 1 = 0; x = -1Solutions: x = -1 and x = 7So Josh's solution is NOT correct.
