Solution for 25n^2+9n+12=0 equation:


Simplifying
25n2 + 9n + 12 = 0

Reorder the terms:
12 + 9n + 25n2 = 0

Solving
12 + 9n + 25n2 = 0

Solving for variable 'n'.

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

Divide each side by '25'.
0.48 + 0.36n + n2 = 0

Move the constant term to the right:

Add '-0.48' to each side of the equation.
0.48 + 0.36n + -0.48 + n2 = 0 + -0.48

Reorder the terms:
0.48 + -0.48 + 0.36n + n2 = 0 + -0.48

Combine like terms: 0.48 + -0.48 = 0.00
0.00 + 0.36n + n2 = 0 + -0.48
0.36n + n2 = 0 + -0.48

Combine like terms: 0 + -0.48 = -0.48
0.36n + n2 = -0.48

The n term is 0.36n.  Take half its coefficient (0.18).
Square it (0.0324) and add it to both sides.

Add '0.0324' to each side of the equation.
0.36n + 0.0324 + n2 = -0.48 + 0.0324

Reorder the terms:
0.0324 + 0.36n + n2 = -0.48 + 0.0324

Combine like terms: -0.48 + 0.0324 = -0.4476
0.0324 + 0.36n + n2 = -0.4476

Factor a perfect square on the left side:
(n + 0.18)(n + 0.18) = -0.4476

Can't calculate square root of the right side.

The solution to this equation could not be determined.
