Question
Solve the following quadratic equations by factorization:
(x - 4)(x + 2) = 0
(x - 4)(x + 2) = 0
✓
Answer
We have
(x - 4)(x + 2) = 0
⇒ either (x - 4) = 0 or (x + 2) = 0
⇒ x = 4 or x = -2
Thus, x = 4 and x = -2 are two roots of the equation (x - 4)(x + 2) = 0
(x - 4)(x + 2) = 0
⇒ either (x - 4) = 0 or (x + 2) = 0
⇒ x = 4 or x = -2
Thus, x = 4 and x = -2 are two roots of the equation (x - 4)(x + 2) = 0
