Solving
29.50 = 19.50 + -50m + 0.25m2

Solving for variable 'm'.

Combine like terms: 29.50 + -19.50 = 10
10 + 50m + -0.25m2 = 19.50 + -50m + 0.25m2 + -19.50 + 50m + -0.25m2

Reorder the terms:
10 + 50m + -0.25m2 = 19.50 + -19.50 + -50m + 50m + 0.25m2 + -0.25m2

Combine like terms: 19.50 + -19.50 = 0.00
10 + 50m + -0.25m2 = 0.00 + -50m + 50m + 0.25m2 + -0.25m2
10 + 50m + -0.25m2 = -50m + 50m + 0.25m2 + -0.25m2

Combine like terms: -50m + 50m = 0
10 + 50m + -0.25m2 = 0 + 0.25m2 + -0.25m2
10 + 50m + -0.25m2 = 0.25m2 + -0.25m2

Combine like terms: 0.25m2 + -0.25m2 = 0.00
10 + 50m + -0.25m2 = 0.00

Begin completing the square.  Divide all terms by
-0.25 the coefficient of the squared term: 

Divide each side by '-0.25'.
-40 + -200m + m2 = 0

Move the constant term to the right:

Add '40' to each side of the equation.
-40 + -200m + 40 + m2 = 0 + 40

Reorder the terms:
-40 + 40 + -200m + m2 = 0 + 40

Combine like terms: -40 + 40 = 0
0 + -200m + m2 = 0 + 40
-200m + m2 = 0 + 40

Combine like terms: 0 + 40 = 40
-200m + m2 = 40

The m term is -200m.  Take half its coefficient (-100).
Square it (10000) and add it to both sides.

Add '10000' to each side of the equation.
-200m + 10000 + m2 = 40 + 10000

Reorder the terms:
10000 + -200m + m2 = 40 + 10000

Combine like terms: 40 + 10000 = 10040
10000 + -200m + m2 = 10040

Factor a perfect square on the left side:
(m + -100)(m + -100) = 10040

Calculate the square root of the right side: 100.199800399

Break this problem into two subproblems by setting 
(m + -100) equal to 100.199800399 and -100.199800399.

Subproblem 1

m + -100 = 100.199800399 Simplifying m + -100 = 100.199800399 Reorder the terms: -100 + m = 100.199800399 Solving -100 + m = 100.199800399 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '100' to each side of the equation. -100 + 100 + m = 100.199800399 + 100 Combine like terms: -100 + 100 = 0 0 + m = 100.199800399 + 100 m = 100.199800399 + 100 Combine like terms: 100.199800399 + 100 = 200.199800399 m = 200.199800399 Simplifying m = 200.199800399

Subproblem 2

m + -100 = -100.199800399 Simplifying m + -100 = -100.199800399 Reorder the terms: -100 + m = -100.199800399 Solving -100 + m = -100.199800399 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '100' to each side of the equation. -100 + 100 + m = -100.199800399 + 100 Combine like terms: -100 + 100 = 0 0 + m = -100.199800399 + 100 m = -100.199800399 + 100 Combine like terms: -100.199800399 + 100 = -0.199800399 m = -0.199800399 Simplifying m = -0.199800399
