x-4=2\sqrt{3} x-4=-2\sqrt{3}
Take the square root of both sides of the equation.
x-4-\left(-4\right)=2\sqrt{3}-\left(-4\right) x-4-\left(-4\right)=-2\sqrt{3}-\left(-4\right)
Add 4 to both sides of the equation.
x=2\sqrt{3}-\left(-4\right) x=-2\sqrt{3}-\left(-4\right)
Subtracting -4 from itself leaves 0.
x=2\sqrt{3}+4
Subtract -4 from 2\sqrt{3}.
x=4-2\sqrt{3}
Subtract -4 from -2\sqrt{3}.
x=2\sqrt{3}+4 x=4-2\sqrt{3}
The equation is now solved.
