Simplifying m2 + 2m + -8 = 3 Reorder the terms: -8 + 2m + m2 = 3 Solving -8 + 2m + m2 = 3 Solving for variable 'm'. Reorder the terms: -8 + -3 + 2m + m2 = 3 + -3 Combine like terms: -8 + -3 = -11 -11 + 2m + m2 = 3 + -3 Combine like terms: 3 + -3 = 0 -11 + 2m + m2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + 2m + 11 + m2 = 0 + 11 Reorder the terms: -11 + 11 + 2m + m2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 2m + m2 = 0 + 11 2m + m2 = 0 + 11 Combine like terms: 0 + 11 = 11 2m + m2 = 11 The m term is 2m. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2m + 1 + m2 = 11 + 1 Reorder the terms: 1 + 2m + m2 = 11 + 1 Combine like terms: 11 + 1 = 12 1 + 2m + m2 = 12 Factor a perfect square on the left side: (m + 1)(m + 1) = 12 Calculate the square root of the right side: 3.464101615 Break this problem into two subproblems by setting (m + 1) equal to 3.464101615 and -3.464101615.Subproblem 1
m + 1 = 3.464101615 Simplifying m + 1 = 3.464101615 Reorder the terms: 1 + m = 3.464101615 Solving 1 + m = 3.464101615 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + m = 3.464101615 + -1 Combine like terms: 1 + -1 = 0 0 + m = 3.464101615 + -1 m = 3.464101615 + -1 Combine like terms: 3.464101615 + -1 = 2.464101615 m = 2.464101615 Simplifying m = 2.464101615Subproblem 2
m + 1 = -3.464101615 Simplifying m + 1 = -3.464101615 Reorder the terms: 1 + m = -3.464101615 Solving 1 + m = -3.464101615 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + m = -3.464101615 + -1 Combine like terms: 1 + -1 = 0 0 + m = -3.464101615 + -1 m = -3.464101615 + -1 Combine like terms: -3.464101615 + -1 = -4.464101615 m = -4.464101615 Simplifying m = -4.464101615Solution
The solution to the problem is based on the solutions from the subproblems. m = {2.464101615, -4.464101615}
