Solution for 5m^2+7m+12=0 equation:


Simplifying
5m2 + 7m + 12 = 0

Reorder the terms:
12 + 7m + 5m2 = 0

Solving
12 + 7m + 5m2 = 0

Solving for variable 'm'.

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

Divide each side by '5'.
2.4 + 1.4m + m2 = 0

Move the constant term to the right:

Add '-2.4' to each side of the equation.
2.4 + 1.4m + -2.4 + m2 = 0 + -2.4

Reorder the terms:
2.4 + -2.4 + 1.4m + m2 = 0 + -2.4

Combine like terms: 2.4 + -2.4 = 0.0
0.0 + 1.4m + m2 = 0 + -2.4
1.4m + m2 = 0 + -2.4

Combine like terms: 0 + -2.4 = -2.4
1.4m + m2 = -2.4

The m term is 1.4m.  Take half its coefficient (0.7).
Square it (0.49) and add it to both sides.

Add '0.49' to each side of the equation.
1.4m + 0.49 + m2 = -2.4 + 0.49

Reorder the terms:
0.49 + 1.4m + m2 = -2.4 + 0.49

Combine like terms: -2.4 + 0.49 = -1.91
0.49 + 1.4m + m2 = -1.91

Factor a perfect square on the left side:
(m + 0.7)(m + 0.7) = -1.91

Can't calculate square root of the right side.

The solution to this equation could not be determined.
