m^2+2m+3=0

Solution for m^2+2m+3=0 equation:

Simplifying
m2 + 2m + 3 = 0

Reorder the terms:
3 + 2m + m2 = 0

Solving
3 + 2m + m2 = 0

Solving for variable 'm'.

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + 2m + -3 + m2 = 0 + -3

Reorder the terms:
3 + -3 + 2m + m2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 2m + m2 = 0 + -3
2m + m2 = 0 + -3

Combine like terms: 0 + -3 = -3
2m + m2 = -3

The m term is 2m.  Take half its coefficient (1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
2m + 1 + m2 = -3 + 1

Reorder the terms:
1 + 2m + m2 = -3 + 1

Combine like terms: -3 + 1 = -2
1 + 2m + m2 = -2

Factor a perfect square on the left side:
(m + 1)(m + 1) = -2

Can't calculate square root of the right side.
