Question #N209
If $x^2 - 2x - 8 = 0$, what is the sum of the solutions to this equation?
A. -2
B. 0
C. 2
D. 8
Correct Answer is: C
The sum of the roots of a quadratic equation in the form ax² + bx + c = 0 is given by -b/a. In this equation, a = 1, b = -2, and c = -8. Therefore, the sum of the solutions is -(-2)/1 = 2.
