Solution for 2n^2+n+10=0 equation:


Simplifying
2n2 + n + 10 = 0

Reorder the terms:
10 + n + 2n2 = 0

Solving
10 + n + 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 + 0.5n + n2 = 0

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + 0.5n + -5 + n2 = 0 + -5

Reorder the terms:
5 + -5 + 0.5n + n2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + 0.5n + n2 = 0 + -5
0.5n + n2 = 0 + -5

Combine like terms: 0 + -5 = -5
0.5n + n2 = -5

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.
0.5n + 0.25 + n2 = -5 + 0.25

Reorder the terms:
0.25 + 0.5n + n2 = -5 + 0.25

Combine like terms: -5 + 0.25 = -4.75
0.25 + 0.5n + n2 = -4.75

Factor a perfect square on the left side:
(n + 0.5)(n + 0.5) = -4.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
