3 + -1m2 + -1(-13 + m2) + (6m2 + m + -10) = 0
3 + -1m2 + (-13 * -1 + m2 * -1) + (6m2 + m + -10) = 0
3 + -1m2 + (13 + -1m2) + (6m2 + m + -10) = 0

Reorder the terms:
3 + -1m2 + 13 + -1m2 + (-10 + m + 6m2) = 0

Remove parenthesis around (-10 + m + 6m2)
3 + -1m2 + 13 + -1m2 + -10 + m + 6m2 = 0

Reorder the terms:
3 + 13 + -10 + m + -1m2 + -1m2 + 6m2 = 0

Combine like terms: 3 + 13 = 16
16 + -10 + m + -1m2 + -1m2 + 6m2 = 0

Combine like terms: 16 + -10 = 6
6 + m + -1m2 + -1m2 + 6m2 = 0

Combine like terms: -1m2 + -1m2 = -2m2
6 + m + -2m2 + 6m2 = 0

Combine like terms: -2m2 + 6m2 = 4m2
6 + m + 4m2 = 0

Solving
6 + m + 4m2 = 0

Solving for variable 'm'.

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

Divide each side by '4'.
1.5 + 0.25m + m2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + 0.25m + -1.5 + m2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + 0.25m + m2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + 0.25m + m2 = 0 + -1.5
0.25m + m2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
0.25m + m2 = -1.5

The m term is m.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
0.25m + 0.25 + m2 = -1.5 + 0.25

Reorder the terms:
0.25 + 0.25m + m2 = -1.5 + 0.25

Combine like terms: -1.5 + 0.25 = -1.25
0.25 + 0.25m + m2 = -1.25

Factor a perfect square on the left side:
(m + 0.5)(m + 0.5) = -1.25

Can't calculate square root of the right side.
