Solve (x-1)^2+5=0

$$( x - 1 ) ^ { 2 } + 5 = 0$$

Solve for x (complex solution)

$$x=-\sqrt{5}i+1\approx 1-2.236067977i$$

$$x=1+\sqrt{5}i\approx 1+2.236067977i$$

Steps by Finding Square Root

Subtracting 5 from itself leaves 0.

$$\left(x-1\right)^{2}=-5$$

Take the square root of both sides of the equation.

$$x-1=\sqrt{5}i x-1=-\sqrt{5}i$$

Add 1 to both sides of the equation.

$$x-1-\left(-1\right)=\sqrt{5}i-\left(-1\right) x-1-\left(-1\right)=-\sqrt{5}i-\left(-1\right)$$

Subtracting -1 from itself leaves 0.

$$x=\sqrt{5}i-\left(-1\right) x=-\sqrt{5}i-\left(-1\right)$$

Subtract -1 from i\sqrt{5}.

$$x=1+\sqrt{5}i$$

Subtract -1 from -i\sqrt{5}.

$$x=-\sqrt{5}i+1$$

The equation is now solved.

$$x=1+\sqrt{5}i x=-\sqrt{5}i+1$$
