2y^2+3y+2=0

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

Simplifying
2y2 + 3y + 2 = 0

Reorder the terms:
2 + 3y + 2y2 = 0

Solving
2 + 3y + 2y2 = 0

Solving for variable 'y'.

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

Divide each side by '2'.
1 + 1.5y + y2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + 1.5y + -1 + y2 = 0 + -1

Reorder the terms:
1 + -1 + 1.5y + y2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 1.5y + y2 = 0 + -1
1.5y + y2 = 0 + -1

Combine like terms: 0 + -1 = -1
1.5y + y2 = -1

The y term is 1.5y.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5y + 0.5625 + y2 = -1 + 0.5625

Reorder the terms:
0.5625 + 1.5y + y2 = -1 + 0.5625

Combine like terms: -1 + 0.5625 = -0.4375
0.5625 + 1.5y + y2 = -0.4375

Factor a perfect square on the left side:
(y + 0.75)(y + 0.75) = -0.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
