–6 and –4,
–4 and 6,
4 and –6,
6 and 4
Answered by maham237 @
Answer:
Value of x for which x² + 2x = 24 is true are -6 and 4 .
Step-by-step explanation:
As given the equation in the question be as follow.
x² + 2x = 24
x² + 2x - 24 = 0
x² + 6x - 4x - 24 = 0
x (x + 6) -4 (x + 6) = 0
(x - 4) (x+6) = 0
x = 4 and x = -6
Therefore the value of x for which x² + 2x = 24 is true are -6 and 4 .
