Solution for 5y^2+y+2=0 equation:


Simplifying
5y2 + y + 2 = 0

Reorder the terms:
2 + y + 5y2 = 0

Solving
2 + y + 5y2 = 0

Solving for variable 'y'.

Begin completing the square.  Divide all terms by
5 the coefficient of the squared term: 

Divide each side by '5'.
0.4 + 0.2y + y2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + 0.2y + -0.4 + y2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + 0.2y + y2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + 0.2y + y2 = 0 + -0.4
0.2y + y2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
0.2y + y2 = -0.4

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.
0.2y + 0.25 + y2 = -0.4 + 0.25

Reorder the terms:
0.25 + 0.2y + y2 = -0.4 + 0.25

Combine like terms: -0.4 + 0.25 = -0.15
0.25 + 0.2y + y2 = -0.15

Factor a perfect square on the left side:
(y + 0.5)(y + 0.5) = -0.15

Can't calculate square root of the right side.

The solution to this equation could not be determined.
