Notice that we have a difference of squares in the numerator of our expression. In the denominator we have a quadratic expression of the form
. So we can factor both numerator and denominator and cancel common terms:
We can conclude that the correct answer is the fourth one:

x=-32
Step-by-step explanation:
expand -2(x+10): -2x-20
x-2x -20=12
add similar elements: x-2x=-x
x-20=12
add 20 to both sides
-x-20+20=12+20
simplify
-x=32
divide both sides by -1
x=-32
