Find any real numbers x which make $\frac { x - 2 } { x ^ { 2 } - 3 x - 10 }$ undefined.
A) $x = - 2 , x = 5$
B) $x = 2 , \quad x = - 5$
C) $x = 2$
D)defined for all real numbers

The given expression is undefined when the denominator is equal to zero. So, we need to solve the equation $x^2-3x-10=0$ to find the values of $x$ that make the denominator zero. By factoring, we get $(x-5)(x+2)=0$, so $x=5$ or $x=-2$. Therefore, the expression is undefined for $x=-2$ and $x=5$. The answer is choice A).
