Solution for 20y^2-13y+3=0 equation:


Simplifying
20y2 + -13y + 3 = 0

Reorder the terms:
3 + -13y + 20y2 = 0

Solving
3 + -13y + 20y2 = 0

Solving for variable 'y'.

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

Divide each side by '20'.
0.15 + -0.65y + y2 = 0

Move the constant term to the right:

Add '-0.15' to each side of the equation.
0.15 + -0.65y + -0.15 + y2 = 0 + -0.15

Reorder the terms:
0.15 + -0.15 + -0.65y + y2 = 0 + -0.15

Combine like terms: 0.15 + -0.15 = 0.00
0.00 + -0.65y + y2 = 0 + -0.15
-0.65y + y2 = 0 + -0.15

Combine like terms: 0 + -0.15 = -0.15
-0.65y + y2 = -0.15

The y term is -0.65y.  Take half its coefficient (-0.325).
Square it (0.105625) and add it to both sides.

Add '0.105625' to each side of the equation.
-0.65y + 0.105625 + y2 = -0.15 + 0.105625

Reorder the terms:
0.105625 + -0.65y + y2 = -0.15 + 0.105625

Combine like terms: -0.15 + 0.105625 = -0.044375
0.105625 + -0.65y + y2 = -0.044375

Factor a perfect square on the left side:
(y + -0.325)(y + -0.325) = -0.044375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
