25y^2-50y+72=0

Solution for 25y^2-50y+72=0 equation:

Simplifying
25y2 + -50y + 72 = 0

Reorder the terms:
72 + -50y + 25y2 = 0

Solving
72 + -50y + 25y2 = 0

Solving for variable 'y'.

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

Divide each side by '25'.
2.88 + -2y + y2 = 0

Move the constant term to the right:

Add '-2.88' to each side of the equation.
2.88 + -2y + -2.88 + y2 = 0 + -2.88

Reorder the terms:
2.88 + -2.88 + -2y + y2 = 0 + -2.88

Combine like terms: 2.88 + -2.88 = 0.00
0.00 + -2y + y2 = 0 + -2.88
-2y + y2 = 0 + -2.88

Combine like terms: 0 + -2.88 = -2.88
-2y + y2 = -2.88

The y term is -2y.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2y + 1 + y2 = -2.88 + 1

Reorder the terms:
1 + -2y + y2 = -2.88 + 1

Combine like terms: -2.88 + 1 = -1.88
1 + -2y + y2 = -1.88

Factor a perfect square on the left side:
(y + -1)(y + -1) = -1.88

Can't calculate square root of the right side.

The solution to this equation could not be determined.
