Subproblem 1

Set the factor '(-12 + -3m + m2)' equal to zero and attempt to solve: Simplifying -12 + -3m + m2 = 0 Solving -12 + -3m + m2 = 0 Begin completing the square. Move the constant term to the right: Add '12' to each side of the equation. -12 + -3m + 12 + m2 = 0 + 12 Reorder the terms: -12 + 12 + -3m + m2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + -3m + m2 = 0 + 12 -3m + m2 = 0 + 12 Combine like terms: 0 + 12 = 12 -3m + m2 = 12 The m term is -3m. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3m + 2.25 + m2 = 12 + 2.25 Reorder the terms: 2.25 + -3m + m2 = 12 + 2.25 Combine like terms: 12 + 2.25 = 14.25 2.25 + -3m + m2 = 14.25 Factor a perfect square on the left side: (m + -1.5)(m + -1.5) = 14.25 Calculate the square root of the right side: 3.774917218 Break this problem into two subproblems by setting (m + -1.5) equal to 3.774917218 and -3.774917218.

Subproblem 1

m + -1.5 = 3.774917218 Simplifying m + -1.5 = 3.774917218 Reorder the terms: -1.5 + m = 3.774917218 Solving -1.5 + m = 3.774917218 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + m = 3.774917218 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + m = 3.774917218 + 1.5 m = 3.774917218 + 1.5 Combine like terms: 3.774917218 + 1.5 = 5.274917218 m = 5.274917218 Simplifying m = 5.274917218

Subproblem 2

m + -1.5 = -3.774917218 Simplifying m + -1.5 = -3.774917218 Reorder the terms: -1.5 + m = -3.774917218 Solving -1.5 + m = -3.774917218 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + m = -3.774917218 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + m = -3.774917218 + 1.5 m = -3.774917218 + 1.5 Combine like terms: -3.774917218 + 1.5 = -2.274917218 m = -2.274917218 Simplifying m = -2.274917218
