\left(x+2\right)^{2}=-53
Subtracting 53 from itself leaves 0.
x+2=\sqrt{53}i x+2=-\sqrt{53}i
Take the square root of both sides of the equation.
x+2-2=\sqrt{53}i-2 x+2-2=-\sqrt{53}i-2
Subtract 2 from both sides of the equation.
x=\sqrt{53}i-2 x=-\sqrt{53}i-2
Subtracting 2 from itself leaves 0.
x=-2+\sqrt{53}i
Subtract 2 from i\sqrt{53}.
x=-\sqrt{53}i-2
Subtract 2 from -i\sqrt{53}.
x=-2+\sqrt{53}i x=-\sqrt{53}i-2
The equation is now solved.
