Answer:
w = -7, -6
Step-by-step explanation:
Solve the equation by factoring:
(w+7)(w+6) = 0
Set each parenthesis equal to zero, and solve for w:
w = -7, -6

Answer: C = -4</h3>
==================================================
Work Shown:
C(x+2) - (x+2)(x-2) = 0
(x+2)(C-(x-2)) = 0
(x+2)(C-x+2) = 0
x+2 = 0 or C-x+2 = 0
x = -2 or x = C+2
If we want one solution only, then we must make C+2 = -2 which solves to C = -4
If C = -4, then x = C+2 = -4+2 = -2 which matches with the first solution mentioned. If C is anything else but -4, then we'd have two different solutions (eg: C = 10 leads to x = C+2 = 12 as the other solution)
