Solution for 3m-2m(m-3)=1 equation:


Simplifying
3m + -2m(m + -3) = 1

Reorder the terms:
3m + -2m(-3 + m) = 1
3m + (-3 * -2m + m * -2m) = 1
3m + (6m + -2m2) = 1

Combine like terms: 3m + 6m = 9m
9m + -2m2 = 1

Solving
9m + -2m2 = 1

Solving for variable 'm'.

Reorder the terms:
-1 + 9m + -2m2 = 1 + -1

Combine like terms: 1 + -1 = 0
-1 + 9m + -2m2 = 0

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
0.5 + -4.5m + m2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -4.5m + -0.5 + m2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -4.5m + m2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -4.5m + m2 = 0 + -0.5
-4.5m + m2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-4.5m + m2 = -0.5

The m term is -4.5m.  Take half its coefficient (-2.25).
Square it (5.0625) and add it to both sides.

Add '5.0625' to each side of the equation.
-4.5m + 5.0625 + m2 = -0.5 + 5.0625

Reorder the terms:
5.0625 + -4.5m + m2 = -0.5 + 5.0625

Combine like terms: -0.5 + 5.0625 = 4.5625
5.0625 + -4.5m + m2 = 4.5625

Factor a perfect square on the left side:
(m + -2.25)(m + -2.25) = 4.5625

Calculate the square root of the right side: 2.136000936

Break this problem into two subproblems by setting 
(m + -2.25) equal to 2.136000936 and -2.136000936.

Subproblem 1

m + -2.25 = 2.136000936 Simplifying m + -2.25 = 2.136000936 Reorder the terms: -2.25 + m = 2.136000936 Solving -2.25 + m = 2.136000936 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + m = 2.136000936 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + m = 2.136000936 + 2.25 m = 2.136000936 + 2.25 Combine like terms: 2.136000936 + 2.25 = 4.386000936 m = 4.386000936 Simplifying m = 4.386000936

Subproblem 2

m + -2.25 = -2.136000936 Simplifying m + -2.25 = -2.136000936 Reorder the terms: -2.25 + m = -2.136000936 Solving -2.25 + m = -2.136000936 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + m = -2.136000936 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + m = -2.136000936 + 2.25 m = -2.136000936 + 2.25 Combine like terms: -2.136000936 + 2.25 = 0.113999064 m = 0.113999064 Simplifying m = 0.113999064
