Question #N467
If $x^2 + 2x - 15 = 0$, what is the sum of the solutions to this equation?
A. -2
B. 2
C. 5
D. 15
Correct Answer is: A
The sum of the solutions to a quadratic equation in the form $ax^2 + bx + c = 0$ is given by $-b/a$. In this case, the sum of the solutions is $-2/1 = -2$. Therefore, the sum of the solutions to the equation $x^2 + 2x - 15 = 0$ is -2.
