For what values of x is x^2 + 2x = 24 true? -6 and -4, -4 and 6, 4 and -6, 6 and 4

Answer: The values of x that satisfy the equation x^2 + 2x = 24 are x = -6 and x = 4.

Algebra

To find the values of x, we need to solve the equation x^2 + 2x – 24 = 0. This is a quadratic equation, and its solutions can be found using the quadratic formula, factoring, or completing the square. In this case, factoring gives us (x – 4)(x + 6) = 0, so x = 4 and x = -6.
