Simplifying 4m2 + 4m + -8 = 1 Reorder the terms: -8 + 4m + 4m2 = 1 Solving -8 + 4m + 4m2 = 1 Solving for variable 'm'. Reorder the terms: -8 + -1 + 4m + 4m2 = 1 + -1 Combine like terms: -8 + -1 = -9 -9 + 4m + 4m2 = 1 + -1 Combine like terms: 1 + -1 = 0 -9 + 4m + 4m2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2.25 + m + m2 = 0 Move the constant term to the right: Add '2.25' to each side of the equation. -2.25 + m + 2.25 + m2 = 0 + 2.25 Reorder the terms: -2.25 + 2.25 + m + m2 = 0 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + m + m2 = 0 + 2.25 m + m2 = 0 + 2.25 Combine like terms: 0 + 2.25 = 2.25 m + m2 = 2.25 The m term is m. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. + 0.25 + m2 = 2.25 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + m2 = 2.25 + 0.25 Combine like terms: 2.25 + 0.25 = 2.5 1.25 + m2 = 2.5 Factor a perfect square on the left side: (m + 0.5)(m + 0.5) = 2.5 Calculate the square root of the right side: 1.58113883 Break this problem into two subproblems by setting (m + 0.5) equal to 1.58113883 and -1.58113883.Subproblem 1
m + 0.5 = 1.58113883 Simplifying m + 0.5 = 1.58113883 Reorder the terms: 0.5 + m = 1.58113883 Solving 0.5 + m = 1.58113883 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + m = 1.58113883 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + m = 1.58113883 + -0.5 m = 1.58113883 + -0.5 Combine like terms: 1.58113883 + -0.5 = 1.08113883 m = 1.08113883 Simplifying m = 1.08113883Subproblem 2
m + 0.5 = -1.58113883 Simplifying m + 0.5 = -1.58113883 Reorder the terms: 0.5 + m = -1.58113883 Solving 0.5 + m = -1.58113883 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + m = -1.58113883 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + m = -1.58113883 + -0.5 m = -1.58113883 + -0.5 Combine like terms: -1.58113883 + -0.5 = -2.08113883 m = -2.08113883 Simplifying m = -2.08113883Solution
The solution to the problem is based on the solutions from the subproblems. m = {1.08113883, -2.08113883}
