x-5=4\sqrt{10} x-5=-4\sqrt{10}
Take the square root of both sides of the equation.
x-5-\left(-5\right)=4\sqrt{10}-\left(-5\right) x-5-\left(-5\right)=-4\sqrt{10}-\left(-5\right)
Add 5 to both sides of the equation.
x=4\sqrt{10}-\left(-5\right) x=-4\sqrt{10}-\left(-5\right)
Subtracting -5 from itself leaves 0.
x=4\sqrt{10}+5
Subtract -5 from 4\sqrt{10}.
x=5-4\sqrt{10}
Subtract -5 from -4\sqrt{10}.
x=4\sqrt{10}+5 x=5-4\sqrt{10}
The equation is now solved.
