n^2+3=2n

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

Simplifying
n2 + 3 = 2n

Reorder the terms:
3 + n2 = 2n

Solving
3 + n2 = 2n

Solving for variable 'n'.

Reorder the terms:
3 + -2n + n2 = 2n + -2n

Combine like terms: 2n + -2n = 0
3 + -2n + n2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -2n + -3 + n2 = 0 + -3

Reorder the terms:
3 + -3 + -2n + n2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -2n + n2 = 0 + -3
-2n + n2 = 0 + -3

Combine like terms: 0 + -3 = -3
-2n + n2 = -3

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

Add '1' to each side of the equation.
-2n + 1 + n2 = -3 + 1

Reorder the terms:
1 + -2n + n2 = -3 + 1

Combine like terms: -3 + 1 = -2
1 + -2n + n2 = -2

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

Can't calculate square root of the right side.
