Simplifying -2m2 + 8m + 4 = 0 Reorder the terms: 4 + 8m + -2m2 = 0 Solving 4 + 8m + -2m2 = 0 Solving for variable 'm'. Factor out the Greatest Common Factor (GCF), '2'. 2(2 + 4m + -1m2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(2 + 4m + -1m2)' equal to zero and attempt to solve: Simplifying 2 + 4m + -1m2 = 0 Solving 2 + 4m + -1m2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -2 + -4m + m2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + -4m + 2 + m2 = 0 + 2 Reorder the terms: -2 + 2 + -4m + m2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -4m + m2 = 0 + 2 -4m + m2 = 0 + 2 Combine like terms: 0 + 2 = 2 -4m + m2 = 2 The m term is -4m. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4m + 4 + m2 = 2 + 4 Reorder the terms: 4 + -4m + m2 = 2 + 4 Combine like terms: 2 + 4 = 6 4 + -4m + m2 = 6 Factor a perfect square on the left side: (m + -2)(m + -2) = 6 Calculate the square root of the right side: 2.449489743 Break this problem into two subproblems by setting (m + -2) equal to 2.449489743 and -2.449489743.Subproblem 1
m + -2 = 2.449489743 Simplifying m + -2 = 2.449489743 Reorder the terms: -2 + m = 2.449489743 Solving -2 + m = 2.449489743 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + m = 2.449489743 + 2 Combine like terms: -2 + 2 = 0 0 + m = 2.449489743 + 2 m = 2.449489743 + 2 Combine like terms: 2.449489743 + 2 = 4.449489743 m = 4.449489743 Simplifying m = 4.449489743Subproblem 2
m + -2 = -2.449489743 Simplifying m + -2 = -2.449489743 Reorder the terms: -2 + m = -2.449489743 Solving -2 + m = -2.449489743 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + m = -2.449489743 + 2 Combine like terms: -2 + 2 = 0 0 + m = -2.449489743 + 2 m = -2.449489743 + 2 Combine like terms: -2.449489743 + 2 = -0.449489743 m = -0.449489743 Simplifying m = -0.449489743Solution
