Question #N939
If $x^{2} - 2x - 15 = 0$, what are the values of $x$?
A. -3 and 5
B. -5 and 3
C. 3 and -5
D. 5 and -3
Correct Answer is: B
The equation $x^{2} - 2x - 15 = 0$ can be factored as $(x - 5)(x + 3) = 0$. Setting each factor equal to zero, we get $x - 5 = 0$ or $x + 3 = 0$. Solving for $x$, we find that $x = 5$ or $x = -3$.
