Solution for b^2+b+2=0 equation:


Simplifying
b2 + b + 2 = 0

Reorder the terms:
2 + b + b2 = 0

Solving
2 + b + b2 = 0

Solving for variable 'b'.

Begin completing the square.

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + b + -2 + b2 = 0 + -2

Reorder the terms:
2 + -2 + b + b2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + b + b2 = 0 + -2
b + b2 = 0 + -2

Combine like terms: 0 + -2 = -2
b + b2 = -2

The b term is b.  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.
b + 0.25 + b2 = -2 + 0.25

Reorder the terms:
0.25 + b + b2 = -2 + 0.25

Combine like terms: -2 + 0.25 = -1.75
0.25 + b + b2 = -1.75

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

Can't calculate square root of the right side.
