Simplifying 3m2 + -15m + -1 = 0 Reorder the terms: -1 + -15m + 3m2 = 0 Solving -1 + -15m + 3m2 = 0 Solving for variable 'm'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -0.3333333333 + -5m + m2 = 0 Move the constant term to the right: Add '0.3333333333' to each side of the equation. -0.3333333333 + -5m + 0.3333333333 + m2 = 0 + 0.3333333333 Reorder the terms: -0.3333333333 + 0.3333333333 + -5m + m2 = 0 + 0.3333333333 Combine like terms: -0.3333333333 + 0.3333333333 = 0.0000000000 0.0000000000 + -5m + m2 = 0 + 0.3333333333 -5m + m2 = 0 + 0.3333333333 Combine like terms: 0 + 0.3333333333 = 0.3333333333 -5m + m2 = 0.3333333333 The m term is -5m. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5m + 6.25 + m2 = 0.3333333333 + 6.25 Reorder the terms: 6.25 + -5m + m2 = 0.3333333333 + 6.25 Combine like terms: 0.3333333333 + 6.25 = 6.5833333333 6.25 + -5m + m2 = 6.5833333333 Factor a perfect square on the left side: (m + -2.5)(m + -2.5) = 6.5833333333 Calculate the square root of the right side: 2.56580072 Break this problem into two subproblems by setting (m + -2.5) equal to 2.56580072 and -2.56580072.Subproblem 1
m + -2.5 = 2.56580072 Simplifying m + -2.5 = 2.56580072 Reorder the terms: -2.5 + m = 2.56580072 Solving -2.5 + m = 2.56580072 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + m = 2.56580072 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + m = 2.56580072 + 2.5 m = 2.56580072 + 2.5 Combine like terms: 2.56580072 + 2.5 = 5.06580072 m = 5.06580072 Simplifying m = 5.06580072Subproblem 2
m + -2.5 = -2.56580072 Simplifying m + -2.5 = -2.56580072 Reorder the terms: -2.5 + m = -2.56580072 Solving -2.5 + m = -2.56580072 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + m = -2.56580072 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + m = -2.56580072 + 2.5 m = -2.56580072 + 2.5 Combine like terms: -2.56580072 + 2.5 = -0.06580072 m = -0.06580072 Simplifying m = -0.06580072Solution
