Question #N236
If $x^2 - 5x + 6 = 0$, what is the sum of the roots of the equation?
A. -5
B. -6
C. 5
D. 6
Correct Answer is: C
For a quadratic equation of the form $ax^2 + bx + c = 0$, the sum of the roots is given by $-b/a$. In this equation, $a = 1$ and $b = -5$, so the sum of the roots is $-(-5)/1 = 5$.
