Answer 1

C. 4 and -6

Explanation:

Answer 2

Value of x for which x² + 2x = 24 is true are -6 and 4 .

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 .
