Simplifying 16m2 + -24m = 9 Reorder the terms: -24m + 16m2 = 9 Solving -24m + 16m2 = 9 Solving for variable 'm'. Reorder the terms: -9 + -24m + 16m2 = 9 + -9 Combine like terms: 9 + -9 = 0 -9 + -24m + 16m2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -0.5625 + -1.5m + m2 = 0 Move the constant term to the right: Add '0.5625' to each side of the equation. -0.5625 + -1.5m + 0.5625 + m2 = 0 + 0.5625 Reorder the terms: -0.5625 + 0.5625 + -1.5m + m2 = 0 + 0.5625 Combine like terms: -0.5625 + 0.5625 = 0.0000 0.0000 + -1.5m + m2 = 0 + 0.5625 -1.5m + m2 = 0 + 0.5625 Combine like terms: 0 + 0.5625 = 0.5625 -1.5m + m2 = 0.5625 The m term is -1.5m. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5m + 0.5625 + m2 = 0.5625 + 0.5625 Reorder the terms: 0.5625 + -1.5m + m2 = 0.5625 + 0.5625 Combine like terms: 0.5625 + 0.5625 = 1.125 0.5625 + -1.5m + m2 = 1.125 Factor a perfect square on the left side: (m + -0.75)(m + -0.75) = 1.125 Calculate the square root of the right side: 1.060660172 Break this problem into two subproblems by setting (m + -0.75) equal to 1.060660172 and -1.060660172.Subproblem 1
m + -0.75 = 1.060660172 Simplifying m + -0.75 = 1.060660172 Reorder the terms: -0.75 + m = 1.060660172 Solving -0.75 + m = 1.060660172 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + m = 1.060660172 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + m = 1.060660172 + 0.75 m = 1.060660172 + 0.75 Combine like terms: 1.060660172 + 0.75 = 1.810660172 m = 1.810660172 Simplifying m = 1.810660172Subproblem 2
m + -0.75 = -1.060660172 Simplifying m + -0.75 = -1.060660172 Reorder the terms: -0.75 + m = -1.060660172 Solving -0.75 + m = -1.060660172 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + m = -1.060660172 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + m = -1.060660172 + 0.75 m = -1.060660172 + 0.75 Combine like terms: -1.060660172 + 0.75 = -0.310660172 m = -0.310660172 Simplifying m = -0.310660172Solution
