Well I'm glad I aced every math course by accident

as for x = -5 Lets give a round of applause, Someone passed grade 6 math

*shrug*

When you go from "5-4x = x^2" to "5-4 = x^2/x", you're officially clueless.

(1+2)^2 = (3)^2 = 9
Yes the exponent is tied into the parentheses.
(1+2)^2 is equal to (1+2)(1+2) correct?
Again lets throw an x in to solve for,
So if you were to put a division in there 18÷(x+2)^2 = 2


Your way:
18÷(x+2)^2 = 2
18÷(x+2)(x+2) = 2 << Notice it is all multiplication and division left but do you do the division first since your going left to right? Or do you finish the simplifying the exponent (ie. The Parentheses in the original question)
18/(x+2)*(x+2)/1 = 2
18 = 2

That doesn't look right to me lol

Other way:
18÷(x+2)^2 = 2
18÷(x+2)(x+2) = 2
18÷(x^2+4x+4) = 2
18/2 = (x^2+4x+4)
9 = x^2 +4x+4
5 = x^2 + 4x
0 = x^2+4x-5
0 = (x+5)(x-1)
Therefore : x = +1 or -5

Looks right to me?

There I fixed it just for you My apoligies for dealing with this in between jobs at work.
