Question #N742
If $x^2 - 4x + 3 = 0$, what is the sum of the solutions to the equation?
A. -1
B. 3
C. 4
D. 7
Correct Answer is: C
The sum of the roots of a quadratic equation in the form $ax^2 + bx + c = 0$ is given by $-b/a$. In this equation, $a = 1$ and $b = -4$. Therefore, the sum of the roots is $-(-4)/1 = 4$.
