Solution for 2n^2-n+11=0 equation:


Simplifying
2n2 + -1n + 11 = 0

Reorder the terms:
11 + -1n + 2n2 = 0

Solving
11 + -1n + 2n2 = 0

Solving for variable 'n'.

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

Divide each side by '2'.
5.5 + -0.5n + n2 = 0

Move the constant term to the right:

Add '-5.5' to each side of the equation.
5.5 + -0.5n + -5.5 + n2 = 0 + -5.5

Reorder the terms:
5.5 + -5.5 + -0.5n + n2 = 0 + -5.5

Combine like terms: 5.5 + -5.5 = 0.0
0.0 + -0.5n + n2 = 0 + -5.5
-0.5n + n2 = 0 + -5.5

Combine like terms: 0 + -5.5 = -5.5
-0.5n + n2 = -5.5

The n term is -0.5n.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5n + 0.0625 + n2 = -5.5 + 0.0625

Reorder the terms:
0.0625 + -0.5n + n2 = -5.5 + 0.0625

Combine like terms: -5.5 + 0.0625 = -5.4375
0.0625 + -0.5n + n2 = -5.4375

Factor a perfect square on the left side:
(n + -0.25)(n + -0.25) = -5.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
