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