Simplifying 5m2 + 17m + 10 = 0 Reorder the terms: 10 + 17m + 5m2 = 0 Solving 10 + 17m + 5m2 = 0 Solving for variable 'm'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 2 + 3.4m + m2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + 3.4m + -2 + m2 = 0 + -2 Reorder the terms: 2 + -2 + 3.4m + m2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 3.4m + m2 = 0 + -2 3.4m + m2 = 0 + -2 Combine like terms: 0 + -2 = -2 3.4m + m2 = -2 The m term is 3.4m. Take half its coefficient (1.7). Square it (2.89) and add it to both sides. Add '2.89' to each side of the equation. 3.4m + 2.89 + m2 = -2 + 2.89 Reorder the terms: 2.89 + 3.4m + m2 = -2 + 2.89 Combine like terms: -2 + 2.89 = 0.89 2.89 + 3.4m + m2 = 0.89 Factor a perfect square on the left side: (m + 1.7)(m + 1.7) = 0.89 Calculate the square root of the right side: 0.943398113 Break this problem into two subproblems by setting (m + 1.7) equal to 0.943398113 and -0.943398113.Subproblem 1
m + 1.7 = 0.943398113 Simplifying m + 1.7 = 0.943398113 Reorder the terms: 1.7 + m = 0.943398113 Solving 1.7 + m = 0.943398113 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-1.7' to each side of the equation. 1.7 + -1.7 + m = 0.943398113 + -1.7 Combine like terms: 1.7 + -1.7 = 0.0 0.0 + m = 0.943398113 + -1.7 m = 0.943398113 + -1.7 Combine like terms: 0.943398113 + -1.7 = -0.756601887 m = -0.756601887 Simplifying m = -0.756601887Subproblem 2
m + 1.7 = -0.943398113 Simplifying m + 1.7 = -0.943398113 Reorder the terms: 1.7 + m = -0.943398113 Solving 1.7 + m = -0.943398113 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-1.7' to each side of the equation. 1.7 + -1.7 + m = -0.943398113 + -1.7 Combine like terms: 1.7 + -1.7 = 0.0 0.0 + m = -0.943398113 + -1.7 m = -0.943398113 + -1.7 Combine like terms: -0.943398113 + -1.7 = -2.643398113 m = -2.643398113 Simplifying m = -2.643398113Solution
The solution to the problem is based on the solutions from the subproblems. m = {-0.756601887, -2.643398113}
