Question

Evaluate the expression below when x = -2

X^2-8/x+6

Can anyone help me (:

Answer 1

So you'll start with (-2)^2 - 8 to find the top, then you'll do (-2) + 6 to find the bottom. After that, simply divide the top you found by the bottom you found

Answer 2

Input 2 for every x:

\(\dfrac{x^2 - 8}{x+6}\)

\(\dfrac{(2)^2 - 8}{2+6}\)

Simplify the exponent:

\(\dfrac{4 - 8}{2+6}\)

Can you do the rest? @JulianoRossiel
