Question

Which of the following equations has exactly the same solutions as (x - 7)(x + 9) = 0?

x ^ 2 = 2x - 63
x ^ 2 + 2x = - 63
x ^ 2 = - 2x + 63
x ^ 2 - 2x - 63 = 0

The equation (x - 7)(x + 9) = 0 can be rewritten as x^2 + 2x - 63 = 0.

Therefore, the equation x^2 + 2x = -63 has exactly the same solutions as (x - 7)(x + 9) = 0.
