Question

find the excluded values in this rational expression.

\\\frac{3x^2 - x - 4}{2x^2 + 9x + 7}\\

\\x \
eq -\frac{?}{ }, \\

enter the smallest excluded value first.

Explanation:

Set the denominator to zero

Using the Excluded Values knowledge point

$$ 2x^2 + 9x + 7 = 0 $$

Factor the quadratic expression

Using the Factoring Trinomials knowledge point

$$
LATEXBLOCK0
$$

Solve for the excluded values

Using the Excluded Values knowledge point

$$
LATEXBLOCK1
$$

Order the values from smallest to largest

Using the Excluded Values knowledge point

$$
LATEXBLOCK2
$$

Answer:

Find the excluded values in this rational expression.
