Answer:
-4 or 12
Step-by-step explanation:
(x + 4)(x - 12) = 0
so
x + 4 = 0 OR x - 12 = 0
x + 4 = 0 leads x = -4
x - 12 = 0 leads x = 12
Answer:
x = -4 or x = 12
Step-by-step explanation:
(x + 4)(x - 12) = 0 means:
(x + 4) = 0 or (x - 12) = 0
x + 4 = 0
Subtract 4 from both sides:
⇒ x + 4 - 4 = 0 - 4
⇒ x = -4
x - 12 = 0
add 12 to both sides:
⇒ x - 12 + 12 = 0 + 12
⇒ x = 12
Therefore the solutions are x = -4 or x = 12
