y^2+3=2y

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

Simplifying
y2 + 3 = 2y

Reorder the terms:
3 + y2 = 2y

Solving
3 + y2 = 2y

Solving for variable 'y'.

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

Combine like terms: 2y + -2y = 0
3 + -2y + y2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -2y + -3 + y2 = 0 + -3

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

Combine like terms: 3 + -3 = 0
0 + -2y + y2 = 0 + -3
-2y + y2 = 0 + -3

Combine like terms: 0 + -3 = -3
-2y + y2 = -3

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 = -3 + 1

Reorder the terms:
1 + -2y + y2 = -3 + 1

Combine like terms: -3 + 1 = -2
1 + -2y + y2 = -2

Factor a perfect square on the left side:
(y + -1)(y + -1) = -2

Can't calculate square root of the right side.
