X^2+1(X+2)=0

Solution for X^2+1(X+2)=0 equation:

Simplifying
X2 + 1(X + 2) = 0

Reorder the terms:
X2 + 1(2 + X) = 0
X2 + (2 * 1 + X * 1) = 0
X2 + (2 + 1X) = 0

Reorder the terms:
2 + 1X + X2 = 0

Solving
2 + 1X + X2 = 0

Solving for variable 'X'.

Begin completing the square.

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + 1X + -2 + X2 = 0 + -2

Reorder the terms:
2 + -2 + 1X + X2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 1X + X2 = 0 + -2
1X + X2 = 0 + -2

Combine like terms: 0 + -2 = -2
1X + X2 = -2

The X term is 1X.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
X + 0.25 + X2 = -2 + 0.25

Reorder the terms:
0.25 + X + X2 = -2 + 0.25

Combine like terms: -2 + 0.25 = -1.75
0.25 + X + X2 = -1.75

Factor a perfect square on the left side:
(X + 0.5)(X + 0.5) = -1.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
