9x+2=5\sqrt{5} 9x+2=-5\sqrt{5}
Take the square root of both sides of the equation.
9x+2-2=5\sqrt{5}-2 9x+2-2=-5\sqrt{5}-2
Subtract 2 from both sides of the equation.
9x=5\sqrt{5}-2 9x=-5\sqrt{5}-2
Subtracting 2 from itself leaves 0.
9x=5\sqrt{5}-2
Subtract 2 from 5\sqrt{5}.
9x=-5\sqrt{5}-2
Subtract 2 from -5\sqrt{5}.
\frac{9x}{9}=\frac{5\sqrt{5}-2}{9} \frac{9x}{9}=\frac{-5\sqrt{5}-2}{9}
Divide both sides by 9.
x=\frac{5\sqrt{5}-2}{9} x=\frac{-5\sqrt{5}-2}{9}
Dividing by 9 undoes the multiplication by 9.
