1) divide by -2 by the associative property of mult.
2) that makes -x+6=(x^2-3x)^(.5), then square both sides
3) that makes, x^2-12x+36=(x^2-3x)
4) then, subtract x^2 and x^2, and divide -3 and -12 to make 4 and subtract 36.
5) that makes 4x=x-36, so subtract x to make 3x=-36 and divide by 3 to make x=-12 but the answer is x=4. What happened?
It seems to me like all the properties of numbers and order of operations were followed
