-4\sqrt{x}+2-2=-18-2
Subtract 2 from both sides of the equation.
-4\sqrt{x}=-18-2
Subtracting 2 from itself leaves 0.
-4\sqrt{x}=-20
Subtract 2 from -18.
\frac{-4\sqrt{x}}{-4}=-\frac{20}{-4}
Divide both sides by -4.
\sqrt{x}=-\frac{20}{-4}
Dividing by -4 undoes the multiplication by -4.
\sqrt{x}=5
Divide -20 by -4.
x=25
Square both sides of the equation.
