Simplifying -7m(-1m + -3) = 45 Reorder the terms: -7m(-3 + -1m) = 45 (-3 * -7m + -1m * -7m) = 45 (21m + 7m2) = 45 Solving 21m + 7m2 = 45 Solving for variable 'm'. Reorder the terms: -45 + 21m + 7m2 = 45 + -45 Combine like terms: 45 + -45 = 0 -45 + 21m + 7m2 = 0 Begin completing the square. Divide all terms by 7 the coefficient of the squared term: Divide each side by '7'. -6.428571429 + 3m + m2 = 0 Move the constant term to the right: Add '6.428571429' to each side of the equation. -6.428571429 + 3m + 6.428571429 + m2 = 0 + 6.428571429 Reorder the terms: -6.428571429 + 6.428571429 + 3m + m2 = 0 + 6.428571429 Combine like terms: -6.428571429 + 6.428571429 = 0.000000000 0.000000000 + 3m + m2 = 0 + 6.428571429 3m + m2 = 0 + 6.428571429 Combine like terms: 0 + 6.428571429 = 6.428571429 3m + m2 = 6.428571429 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 = 6.428571429 + 2.25 Reorder the terms: 2.25 + 3m + m2 = 6.428571429 + 2.25 Combine like terms: 6.428571429 + 2.25 = 8.678571429 2.25 + 3m + m2 = 8.678571429 Factor a perfect square on the left side: (m + 1.5)(m + 1.5) = 8.678571429 Calculate the square root of the right side: 2.945941518 Break this problem into two subproblems by setting (m + 1.5) equal to 2.945941518 and -2.945941518.Subproblem 1
m + 1.5 = 2.945941518 Simplifying m + 1.5 = 2.945941518 Reorder the terms: 1.5 + m = 2.945941518 Solving 1.5 + m = 2.945941518 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 = 2.945941518 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + m = 2.945941518 + -1.5 m = 2.945941518 + -1.5 Combine like terms: 2.945941518 + -1.5 = 1.445941518 m = 1.445941518 Simplifying m = 1.445941518Subproblem 2
m + 1.5 = -2.945941518 Simplifying m + 1.5 = -2.945941518 Reorder the terms: 1.5 + m = -2.945941518 Solving 1.5 + m = -2.945941518 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 = -2.945941518 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + m = -2.945941518 + -1.5 m = -2.945941518 + -1.5 Combine like terms: -2.945941518 + -1.5 = -4.445941518 m = -4.445941518 Simplifying m = -4.445941518Solution
