Question

find the excluded values in this rational expression.

\\\frac{3x^2 - x + 7}{x^2 + 9x + 8}\\

\\(x \
eq ?, \\)

enter the smallest excluded value first.

Explanation:

Set the denominator to zero

Using the Excluded Values knowledge point

$$ x^2 + 9x + 8 = 0 $$

Factor the quadratic trinomial

Using the Factoring Trinomials knowledge point

$$ (x + 8)(x + 1) = 0 $$

Solve for the excluded values

Using the Excluded Values knowledge point

$$
LATEXBLOCK0
$$

Comparing the values: \(-8 < -1\).

Answer:

Find the excluded values in this rational expression.

$$\frac{3x^2 - x + 7}{x^2 + 9x + 8}$$
