Answer:
x = 2 or
x = -7
Step-by-step explanation:
(x - 2)(x + 7) = 0
x - 2 = 0
Add 2 to both sides
x - 2 + 2 = 2 + 0
x = 2
OR
x + 7 = 0
Subtract 7 from both sides
x + 7 - 7 = 0-7
x = -7
Therefore
x = 2 or
x = -7

80 has 9 factor because 1×80=80. 2×40-80. 4×20=80. 5×16=80. 8×10=80 . 10 ×8=80. 20×4=80. 40×2=80. and 80×1=80 80 is greater than 20 and that has 9 factors
