y^2+y+30=0

Solution for y^2+y+30=0 equation:

Simplifying
y2 + y + 30 = 0

Reorder the terms:
30 + y + y2 = 0

Solving
30 + y + y2 = 0

Solving for variable 'y'.

Begin completing the square.

Move the constant term to the right:

Add '-30' to each side of the equation.
30 + y + -30 + y2 = 0 + -30

Reorder the terms:
30 + -30 + y + y2 = 0 + -30

Combine like terms: 30 + -30 = 0
0 + y + y2 = 0 + -30
y + y2 = 0 + -30

Combine like terms: 0 + -30 = -30
y + y2 = -30

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 = -30 + 0.25

Reorder the terms:
0.25 + y + y2 = -30 + 0.25

Combine like terms: -30 + 0.25 = -29.75
0.25 + y + y2 = -29.75

Factor a perfect square on the left side:
(y + 0.5)(y + 0.5) = -29.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
