Question

Evaluate and simplify

Answer 1

Answer:

$\frac{-3}{-26}$

Step-by-step explanation:

$\frac{-x-8}{x^{2}-4x-21}$ is what you are looking for.

So with x = -5, it would look like this

$\frac{-(-5)-8}{-5^{2}-(-5)4-21}$

Simple math now.

-(-5) is 5

$-5^{2} = -25$

-5 * -4 = 20.

So it should be $\frac{5-8}{-25+20-21}$

5-8=-3

-25+20-21 = -26

So the answer is$\frac{-3}{-26}$
