8n2 + n = -11

Reorder the terms:
n + 8n2 = -11

Solving
n + 8n2 = -11

Solving for variable 'n'.

Reorder the terms:
11 + n + 8n2 = -11 + 11

Combine like terms: -11 + 11 = 0
11 + n + 8n2 = 0

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

Divide each side by '8'.
1.375 + 0.125n + n2 = 0

Move the constant term to the right:

Add '-1.375' to each side of the equation.
1.375 + 0.125n + -1.375 + n2 = 0 + -1.375

Reorder the terms:
1.375 + -1.375 + 0.125n + n2 = 0 + -1.375

Combine like terms: 1.375 + -1.375 = 0.000
0.000 + 0.125n + n2 = 0 + -1.375
0.125n + n2 = 0 + -1.375

Combine like terms: 0 + -1.375 = -1.375
0.125n + n2 = -1.375

The n term is n.  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.
0.125n + 0.25 + n2 = -1.375 + 0.25

Reorder the terms:
0.25 + 0.125n + n2 = -1.375 + 0.25

Combine like terms: -1.375 + 0.25 = -1.125
0.25 + 0.125n + n2 = -1.125

Factor a perfect square on the left side:
(n + 0.5)(n + 0.5) = -1.125

Can't calculate square root of the right side.
