Solution for y(y)+y+1=0 equation:


Simplifying
y(y) + y + 1 = 0

Multiply y * y
y2 + y + 1 = 0

Reorder the terms:
1 + y + y2 = 0

Solving
1 + y + y2 = 0

Solving for variable 'y'.

Begin completing the square.

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + y + -1 + y2 = 0 + -1

Reorder the terms:
1 + -1 + y + y2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + y + y2 = 0 + -1
y + y2 = 0 + -1

Combine like terms: 0 + -1 = -1
y + y2 = -1

The y term is y.  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.
y + 0.25 + y2 = -1 + 0.25

Reorder the terms:
0.25 + y + y2 = -1 + 0.25

Combine like terms: -1 + 0.25 = -0.75
0.25 + y + y2 = -0.75

Factor a perfect square on the left side:
(y + 0.5)(y + 0.5) = -0.75

Can't calculate square root of the right side.
