Answer:

\Huge \boxed{x=-1}

Step-by-step explanation:

x^2+2x=-1

Adding 1 to both sides of the equation.

x^2+2x+1=-1+1

x^2 +2x+1=0

Factoring the left side of the equation.

x^2 +1x+1x+1=0

x(x+1)+1(x+1)=0

(x+1)(x+1) = 0

(x+1)^2 =0

Taking the square root of both sides of the equation.

\sqrt{(x+1)^2} =\sqrt{0}

x+1=0

Subtracting 1 from both sides of the equation.

x+1-1=0-1

x=-1
