Solution for n^2=3n-11 equation:


Simplifying
n2 = 3n + -11

Reorder the terms:
n2 = -11 + 3n

Solving
n2 = -11 + 3n

Solving for variable 'n'.

Reorder the terms:
11 + -3n + n2 = -11 + 3n + 11 + -3n

Reorder the terms:
11 + -3n + n2 = -11 + 11 + 3n + -3n

Combine like terms: -11 + 11 = 0
11 + -3n + n2 = 0 + 3n + -3n
11 + -3n + n2 = 3n + -3n

Combine like terms: 3n + -3n = 0
11 + -3n + n2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-11' to each side of the equation.
11 + -3n + -11 + n2 = 0 + -11

Reorder the terms:
11 + -11 + -3n + n2 = 0 + -11

Combine like terms: 11 + -11 = 0
0 + -3n + n2 = 0 + -11
-3n + n2 = 0 + -11

Combine like terms: 0 + -11 = -11
-3n + n2 = -11

The n term is -3n.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3n + 2.25 + n2 = -11 + 2.25

Reorder the terms:
2.25 + -3n + n2 = -11 + 2.25

Combine like terms: -11 + 2.25 = -8.75
2.25 + -3n + n2 = -8.75

Factor a perfect square on the left side:
(n + -1.5)(n + -1.5) = -8.75

Can't calculate square root of the right side.
