Solution for 25000=1.25n(12-n) equation:


Simplifying
25000 = 1.25n(12 + -1n)
25000 = (12 * 1.25n + -1n * 1.25n)
25000 = (15n + -1.25n2)

Solving
25000 = 15n + -1.25n2

Solving for variable 'n'.

Reorder the terms:
25000 + -15n + 1.25n2 = 15n + -15n + -1.25n2 + 1.25n2

Combine like terms: 15n + -15n = 0
25000 + -15n + 1.25n2 = 0 + -1.25n2 + 1.25n2
25000 + -15n + 1.25n2 = -1.25n2 + 1.25n2

Combine like terms: -1.25n2 + 1.25n2 = 0.00
25000 + -15n + 1.25n2 = 0.00

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

Divide each side by '1.25'.
20000 + -12n + n2 = 0

Move the constant term to the right:

Add '-20000' to each side of the equation.
20000 + -12n + -20000 + n2 = 0 + -20000

Reorder the terms:
20000 + -20000 + -12n + n2 = 0 + -20000

Combine like terms: 20000 + -20000 = 0
0 + -12n + n2 = 0 + -20000
-12n + n2 = 0 + -20000

Combine like terms: 0 + -20000 = -20000
-12n + n2 = -20000

The n term is -12n.  Take half its coefficient (-6).
Square it (36) and add it to both sides.

Add '36' to each side of the equation.
-12n + 36 + n2 = -20000 + 36

Reorder the terms:
36 + -12n + n2 = -20000 + 36

Combine like terms: -20000 + 36 = -19964
36 + -12n + n2 = -19964

Factor a perfect square on the left side:
(n + -6)(n + -6) = -19964

Can't calculate square root of the right side.

The solution to this equation could not be determined.
