Question #N343
If $x^2 - 2x - 8 = 0$, what is the sum of the solutions to the equation?
A. -2
B. 2
C. 0
D. 8
Correct Answer is: B
The sum of the solutions to a quadratic equation of the form $ax^2 + bx + c = 0$ is given by $-b/a$. In this case, $a = 1$, $b = -2$, and $c = -8$. Therefore, the sum of the solutions is $-(-2)/1 = 2$.
