Simplifying m2 + 9m + -8 = 0 Reorder the terms: -8 + 9m + m2 = 0 Solving -8 + 9m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '8' to each side of the equation. -8 + 9m + 8 + m2 = 0 + 8 Reorder the terms: -8 + 8 + 9m + m2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + 9m + m2 = 0 + 8 9m + m2 = 0 + 8 Combine like terms: 0 + 8 = 8 9m + m2 = 8 The m term is 9m. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9m + 20.25 + m2 = 8 + 20.25 Reorder the terms: 20.25 + 9m + m2 = 8 + 20.25 Combine like terms: 8 + 20.25 = 28.25 20.25 + 9m + m2 = 28.25 Factor a perfect square on the left side: (m + 4.5)(m + 4.5) = 28.25 Calculate the square root of the right side: 5.315072906 Break this problem into two subproblems by setting (m + 4.5) equal to 5.315072906 and -5.315072906.Subproblem 1
m + 4.5 = 5.315072906 Simplifying m + 4.5 = 5.315072906 Reorder the terms: 4.5 + m = 5.315072906 Solving 4.5 + m = 5.315072906 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + m = 5.315072906 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + m = 5.315072906 + -4.5 m = 5.315072906 + -4.5 Combine like terms: 5.315072906 + -4.5 = 0.815072906 m = 0.815072906 Simplifying m = 0.815072906Subproblem 2
m + 4.5 = -5.315072906 Simplifying m + 4.5 = -5.315072906 Reorder the terms: 4.5 + m = -5.315072906 Solving 4.5 + m = -5.315072906 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + m = -5.315072906 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + m = -5.315072906 + -4.5 m = -5.315072906 + -4.5 Combine like terms: -5.315072906 + -4.5 = -9.815072906 m = -9.815072906 Simplifying m = -9.815072906Solution
The solution to the problem is based on the solutions from the subproblems. m = {0.815072906, -9.815072906}
