Solution for n*(n+7)=-36 equation:


Simplifying
n(n + 7) = -36

Reorder the terms:
n(7 + n) = -36
(7 * n + n * n) = -36
(7n + n2) = -36

Solving
7n + n2 = -36

Solving for variable 'n'.

Reorder the terms:
36 + 7n + n2 = -36 + 36

Combine like terms: -36 + 36 = 0
36 + 7n + n2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-36' to each side of the equation.
36 + 7n + -36 + n2 = 0 + -36

Reorder the terms:
36 + -36 + 7n + n2 = 0 + -36

Combine like terms: 36 + -36 = 0
0 + 7n + n2 = 0 + -36
7n + n2 = 0 + -36

Combine like terms: 0 + -36 = -36
7n + n2 = -36

The n term is 7n.  Take half its coefficient (3.5).
Square it (12.25) and add it to both sides.

Add '12.25' to each side of the equation.
7n + 12.25 + n2 = -36 + 12.25

Reorder the terms:
12.25 + 7n + n2 = -36 + 12.25

Combine like terms: -36 + 12.25 = -23.75
12.25 + 7n + n2 = -23.75

Factor a perfect square on the left side:
(n + 3.5)(n + 3.5) = -23.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
