Solution for 19-n(-5-n)=-10 equation:


Simplifying
19 + -1n(-5 + -1n) = -10
19 + (-5 * -1n + -1n * -1n) = -10
19 + (5n + 1n2) = -10

Solving
19 + 5n + 1n2 = -10

Solving for variable 'n'.

Reorder the terms:
19 + 10 + 5n + 1n2 = -10 + 10

Combine like terms: 19 + 10 = 29
29 + 5n + 1n2 = -10 + 10

Combine like terms: -10 + 10 = 0
29 + 5n + 1n2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-29' to each side of the equation.
29 + 5n + -29 + n2 = 0 + -29

Reorder the terms:
29 + -29 + 5n + n2 = 0 + -29

Combine like terms: 29 + -29 = 0
0 + 5n + n2 = 0 + -29
5n + n2 = 0 + -29

Combine like terms: 0 + -29 = -29
5n + n2 = -29

The n term is 5n.  Take half its coefficient (2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
5n + 6.25 + n2 = -29 + 6.25
