Simplifying -4m2 + 6m + -16 = -15 Reorder the terms: -16 + 6m + -4m2 = -15 Solving -16 + 6m + -4m2 = -15 Solving for variable 'm'. Reorder the terms: -16 + 15 + 6m + -4m2 = -15 + 15 Combine like terms: -16 + 15 = -1 -1 + 6m + -4m2 = -15 + 15 Combine like terms: -15 + 15 = 0 -1 + 6m + -4m2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 0.25 + -1.5m + m2 = 0 Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + -1.5m + -0.25 + m2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + -1.5m + m2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + -1.5m + m2 = 0 + -0.25 -1.5m + m2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 -1.5m + m2 = -0.25 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 = -0.25 + 0.5625 Reorder the terms: 0.5625 + -1.5m + m2 = -0.25 + 0.5625 Combine like terms: -0.25 + 0.5625 = 0.3125 0.5625 + -1.5m + m2 = 0.3125 Factor a perfect square on the left side: (m + -0.75)(m + -0.75) = 0.3125 Calculate the square root of the right side: 0.559016994 Break this problem into two subproblems by setting (m + -0.75) equal to 0.559016994 and -0.559016994.Subproblem 1
m + -0.75 = 0.559016994 Simplifying m + -0.75 = 0.559016994 Reorder the terms: -0.75 + m = 0.559016994 Solving -0.75 + m = 0.559016994 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 = 0.559016994 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + m = 0.559016994 + 0.75 m = 0.559016994 + 0.75 Combine like terms: 0.559016994 + 0.75 = 1.309016994 m = 1.309016994 Simplifying m = 1.309016994Subproblem 2
m + -0.75 = -0.559016994 Simplifying m + -0.75 = -0.559016994 Reorder the terms: -0.75 + m = -0.559016994 Solving -0.75 + m = -0.559016994 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 = -0.559016994 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + m = -0.559016994 + 0.75 m = -0.559016994 + 0.75 Combine like terms: -0.559016994 + 0.75 = 0.190983006 m = 0.190983006 Simplifying m = 0.190983006Solution
