Solution for y^2+6y-9-6y+18+13-y=0 equation:


Simplifying
y2 + 6y + -9 + -6y + 18 + 13 + -1y = 0

Reorder the terms:
-9 + 18 + 13 + 6y + -6y + -1y + y2 = 0

Combine like terms: -9 + 18 = 9
9 + 13 + 6y + -6y + -1y + y2 = 0

Combine like terms: 9 + 13 = 22
22 + 6y + -6y + -1y + y2 = 0

Combine like terms: 6y + -6y = 0
22 + 0 + -1y + y2 = 0
22 + -1y + y2 = 0

Solving
22 + -1y + y2 = 0

Solving for variable 'y'.

Begin completing the square.

Move the constant term to the right:

Add '-22' to each side of the equation.
22 + -1y + -22 + y2 = 0 + -22

Reorder the terms:
22 + -22 + -1y + y2 = 0 + -22

Combine like terms: 22 + -22 = 0
0 + -1y + y2 = 0 + -22
-1y + y2 = 0 + -22

Combine like terms: 0 + -22 = -22
-1y + y2 = -22

The y term is -1y.  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.
-1y + 0.25 + y2 = -22 + 0.25

Reorder the terms:
0.25 + -1y + y2 = -22 + 0.25

Combine like terms: -22 + 0.25 = -21.75
0.25 + -1y + y2 = -21.75

Factor a perfect square on the left side:
(y + -0.5)(y + -0.5) = -21.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
