Subproblem 1

Set the factor 'm' equal to zero and attempt to solve: Simplifying m = 0 Solving m = 0 Move all terms containing m to the left, all other terms to the right. Simplifying m = 0

Subproblem 2

Set the factor '(-25 + -6m + m2)' equal to zero and attempt to solve: Simplifying -25 + -6m + m2 = 0 Solving -25 + -6m + m2 = 0 Begin completing the square. Move the constant term to the right: Add '25' to each side of the equation. -25 + -6m + 25 + m2 = 0 + 25 Reorder the terms: -25 + 25 + -6m + m2 = 0 + 25 Combine like terms: -25 + 25 = 0 0 + -6m + m2 = 0 + 25 -6m + m2 = 0 + 25 Combine like terms: 0 + 25 = 25 -6m + m2 = 25 The m term is -6m. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6m + 9 + m2 = 25 + 9 Reorder the terms: 9 + -6m + m2 = 25 + 9 Combine like terms: 25 + 9 = 34 9 + -6m + m2 = 34 Factor a perfect square on the left side: (m + -3)(m + -3) = 34 Calculate the square root of the right side: 5.830951895 Break this problem into two subproblems by setting (m + -3) equal to 5.830951895 and -5.830951895.

Subproblem 1

m + -3 = 5.830951895 Simplifying m + -3 = 5.830951895 Reorder the terms: -3 + m = 5.830951895 Solving -3 + m = 5.830951895 Solving for variable 'm'.
