Question

Quizplus · Accepted Answer

The values excluded from the expression are those that make the denominator equal to zero. Factoring the denominator $x^2 - 7x + 10$ gives $(x - 5)(x - 2)$. Setting each factor equal to zero gives the values $x = 5$ and $x = 2$, which are the values that cannot be used in the original expression.
