Select the correct answer. For which quotient is x=7 an excluded value?
Lisa [10]

Answer:

\frac{7x}{x^2 - 10x + 21} / \frac{x + 7}{7}

Step-by-step explanation:

Given

See attachment

To answer this question, we start by equating the denominators of each option to 0; then, solve for x

(a):

\frac{7x}{x^2 - 10x + 21} / \frac{x + 7}{7}

This gives

\frac{7x}{x^2 - 10x + 21} * \frac{7}{x + 7}

Set the denominator to 0

(x^2 - 10x + 21)(x + 7) = 0

Solve for x

(x^2 - 7x - 3x + 21)(x + 7) = 0

Factorize:

(x(x - 7) - 3(x - 7))(x + 7) = 0

(x - 7)(x - 3)(x + 7) = 0

This implies that:

x = 7\ or\ x = 3\ or\ x = -7

From above, one of the values of x is 7.

This implies that x = 7 is an excluded value for this quotient.

<em>Other options do not need to be checked, since there is only one answer.</em>
