-Find any real numbers for which the following expression is undefined. $\frac { x + 6 } { x ^ { 2 } + 8 x - 48 }$
A)x = -6
B)x = -6, x = -12, x = 4
C)x = -12, x = 4
D)x = -4, x = 12

Question

Quizplus · Accepted Answer

The expression is undefined when the denominator equals zero. Factoring the denominator gives $x^2 + 8x - 48 = (x + 12)(x - 4)$. Setting each factor equal to zero gives $x = -12$ and $x = 4$, so the expression is undefined for $x = -12$ and $x = 4$.
