Solution for 25m^2+8m+64=0 equation:


Simplifying
25m2 + 8m + 64 = 0

Reorder the terms:
64 + 8m + 25m2 = 0

Solving
64 + 8m + 25m2 = 0

Solving for variable 'm'.

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

Divide each side by '25'.
2.56 + 0.32m + m2 = 0

Move the constant term to the right:

Add '-2.56' to each side of the equation.
2.56 + 0.32m + -2.56 + m2 = 0 + -2.56

Reorder the terms:
2.56 + -2.56 + 0.32m + m2 = 0 + -2.56

Combine like terms: 2.56 + -2.56 = 0.00
0.00 + 0.32m + m2 = 0 + -2.56
0.32m + m2 = 0 + -2.56

Combine like terms: 0 + -2.56 = -2.56
0.32m + m2 = -2.56

The m term is 0.32m.  Take half its coefficient (0.16).
Square it (0.0256) and add it to both sides.

Add '0.0256' to each side of the equation.
0.32m + 0.0256 + m2 = -2.56 + 0.0256

Reorder the terms:
0.0256 + 0.32m + m2 = -2.56 + 0.0256

Combine like terms: -2.56 + 0.0256 = -2.5344
0.0256 + 0.32m + m2 = -2.5344

Factor a perfect square on the left side:
(m + 0.16)(m + 0.16) = -2.5344

Can't calculate square root of the right side.

The solution to this equation could not be determined.
