\left(x+10\right)^{2}-63+63=63
Add 63 to both sides of the equation.
\left(x+10\right)^{2}=63
Subtracting 63 from itself leaves 0.
x+10=3\sqrt{7} x+10=-3\sqrt{7}
Take the square root of both sides of the equation.
x+10-10=3\sqrt{7}-10 x+10-10=-3\sqrt{7}-10
Subtract 10 from both sides of the equation.
x=3\sqrt{7}-10 x=-3\sqrt{7}-10
Subtracting 10 from itself leaves 0.
