Simplifying m2 + 3m + -17 = 0 Reorder the terms: -17 + 3m + m2 = 0 Solving -17 + 3m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '17' to each side of the equation. -17 + 3m + 17 + m2 = 0 + 17 Reorder the terms: -17 + 17 + 3m + m2 = 0 + 17 Combine like terms: -17 + 17 = 0 0 + 3m + m2 = 0 + 17 3m + m2 = 0 + 17 Combine like terms: 0 + 17 = 17 3m + m2 = 17 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 = 17 + 2.25 Reorder the terms: 2.25 + 3m + m2 = 17 + 2.25 Combine like terms: 17 + 2.25 = 19.25 2.25 + 3m + m2 = 19.25 Factor a perfect square on the left side: (m + 1.5)(m + 1.5) = 19.25 Calculate the square root of the right side: 4.387482194 Break this problem into two subproblems by setting (m + 1.5) equal to 4.387482194 and -4.387482194.Subproblem 1
m + 1.5 = 4.387482194 Simplifying m + 1.5 = 4.387482194 Reorder the terms: 1.5 + m = 4.387482194 Solving 1.5 + m = 4.387482194 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 = 4.387482194 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + m = 4.387482194 + -1.5 m = 4.387482194 + -1.5 Combine like terms: 4.387482194 + -1.5 = 2.887482194 m = 2.887482194 Simplifying m = 2.887482194Subproblem 2
m + 1.5 = -4.387482194 Simplifying m + 1.5 = -4.387482194 Reorder the terms: 1.5 + m = -4.387482194 Solving 1.5 + m = -4.387482194 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 = -4.387482194 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + m = -4.387482194 + -1.5 m = -4.387482194 + -1.5 Combine like terms: -4.387482194 + -1.5 = -5.887482194 m = -5.887482194 Simplifying m = -5.887482194Solution
The solution to the problem is based on the solutions from the subproblems. m = {2.887482194, -5.887482194}
