# What are the excluded values of f(t) = (t+1)/(t^2+3t+2)?

Sep 4, 2016

$t \ne - 2 , - 1$

#### Explanation:

These will occur when the denominator is rendered $0$.

We can find the excluded values by setting the denominator to $0$ and solving for the variable.

${t}^{2} + 3 t + 2 = 0$

$\left(t + 2\right) \left(t + 1\right) = 0$

$t = - 2 \mathmr{and} - 1$

Hence, $t \ne - 2 \mathmr{and} - 1$.

Hopefully this helps!
