Answer:
10
Step-by-step explanation:
given

we first need to simplify the expression before we find it's value when s=-3
positive times negative=negative
so the equation becomes

substituting s=-3 into the equation.

=

=the negatives cancel out leaving

2/X^2=4/X+1 times by both denominators
2(x+1)=4(x^2)
2x+2=4x^2
4x^2-2x-2=0
(2x+1)(2x-2)=0
x=2x+1 or 2x-2
x=-1/2 or 1
The answer to that question is B.
