Simplifying m2 + 17m + 14 = 0 Reorder the terms: 14 + 17m + m2 = 0 Solving 14 + 17m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '-14' to each side of the equation. 14 + 17m + -14 + m2 = 0 + -14 Reorder the terms: 14 + -14 + 17m + m2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + 17m + m2 = 0 + -14 17m + m2 = 0 + -14 Combine like terms: 0 + -14 = -14 17m + m2 = -14 The m term is 17m. Take half its coefficient (8.5). Square it (72.25) and add it to both sides. Add '72.25' to each side of the equation. 17m + 72.25 + m2 = -14 + 72.25 Reorder the terms: 72.25 + 17m + m2 = -14 + 72.25 Combine like terms: -14 + 72.25 = 58.25 72.25 + 17m + m2 = 58.25 Factor a perfect square on the left side: (m + 8.5)(m + 8.5) = 58.25 Calculate the square root of the right side: 7.632168761 Break this problem into two subproblems by setting (m + 8.5) equal to 7.632168761 and -7.632168761.Subproblem 1
m + 8.5 = 7.632168761 Simplifying m + 8.5 = 7.632168761 Reorder the terms: 8.5 + m = 7.632168761 Solving 8.5 + m = 7.632168761 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-8.5' to each side of the equation. 8.5 + -8.5 + m = 7.632168761 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + m = 7.632168761 + -8.5 m = 7.632168761 + -8.5 Combine like terms: 7.632168761 + -8.5 = -0.867831239 m = -0.867831239 Simplifying m = -0.867831239Subproblem 2
m + 8.5 = -7.632168761 Simplifying m + 8.5 = -7.632168761 Reorder the terms: 8.5 + m = -7.632168761 Solving 8.5 + m = -7.632168761 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-8.5' to each side of the equation. 8.5 + -8.5 + m = -7.632168761 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + m = -7.632168761 + -8.5 m = -7.632168761 + -8.5 Combine like terms: -7.632168761 + -8.5 = -16.132168761 m = -16.132168761 Simplifying m = -16.132168761Solution
The solution to the problem is based on the solutions from the subproblems. m = {-0.867831239, -16.132168761}
