Question #N640
If $x^2 - 2x - 8 = 0$, what is the sum of the solutions to the equation?
A. -2
B. 2
C. -6
D. 6
Correct Answer is: B
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, a = 1, b = -2, and c = -8. So, the sum of the solutions is -(-2)/1 = 2.
