Answer:
yawn. ok.
(√x+6)-4=x
(√x+6)=x+4
square the entire equation
x+6=(X^2)+16+4x
6=X squared +16 + 3x
(x^2)+3x-10
after this, use vieta's fórmula, quadratic roots formula, or make it a quadratic to identify the roots. then find the opposite of the x-... or x+... and then you have your answer
when I used quadratic roots formula (which I am strong at), I got x=-5 and x=2
