\frac{y^{2} - y + 5}{y + 4}

$\frac{y^{2} - y + 5}{y + 4}$

Step 1

Set the denominator in

\frac{y^{2} - y + 5}{y + 4}

$\frac{y^{2} - y + 5}{y + 4}$ equal to

0

$0$ to find where the expression is undefined.

y + 4 = 0

$y + 4 = 0$

Step 2

Subtract

4

$4$ from both sides of the equation.

y = - 4

$y = - 4$

Step 3

[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]
