Question

Evaluate the expression below when x = -2.

x^2 − 8
x + 6
A.
-3
B.
-1
C.
1/2
D.
3/2

Answer 1

-1

Explanation:

(x^2 - 8) / ( x+6)

Let x = -2

(( -2)^2 -8)/ ( -2+6)

(4-8)/(-2+6)

-4/4

-1

Answer 2

( -1 )

Explanation:

Given that,

`((x^(2)-8) )/((x+6))`

Also given that,

x = -2

So, to solve the above expression, you have to replace x with ( - 2 )

Let us solve.

`((x^(2)-8) )/((x+6))`

`(((-2^(2))-8) )/((-2+6))`

`(4-8 )/((4))`

`(-4 )/((4))`

`-1`
