Simplifying 4m2 + 30m + 16 = 0 Reorder the terms: 16 + 30m + 4m2 = 0 Solving 16 + 30m + 4m2 = 0 Solving for variable 'm'. Factor out the Greatest Common Factor (GCF), '2'. 2(8 + 15m + 2m2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(8 + 15m + 2m2)' equal to zero and attempt to solve: Simplifying 8 + 15m + 2m2 = 0 Solving 8 + 15m + 2m2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 4 + 7.5m + m2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + 7.5m + -4 + m2 = 0 + -4 Reorder the terms: 4 + -4 + 7.5m + m2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 7.5m + m2 = 0 + -4 7.5m + m2 = 0 + -4 Combine like terms: 0 + -4 = -4 7.5m + m2 = -4 The m term is 7.5m. Take half its coefficient (3.75). Square it (14.0625) and add it to both sides. Add '14.0625' to each side of the equation. 7.5m + 14.0625 + m2 = -4 + 14.0625 Reorder the terms: 14.0625 + 7.5m + m2 = -4 + 14.0625 Combine like terms: -4 + 14.0625 = 10.0625 14.0625 + 7.5m + m2 = 10.0625 Factor a perfect square on the left side: (m + 3.75)(m + 3.75) = 10.0625 Calculate the square root of the right side: 3.172144385 Break this problem into two subproblems by setting (m + 3.75) equal to 3.172144385 and -3.172144385.Subproblem 1
m + 3.75 = 3.172144385 Simplifying m + 3.75 = 3.172144385 Reorder the terms: 3.75 + m = 3.172144385 Solving 3.75 + m = 3.172144385 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-3.75' to each side of the equation. 3.75 + -3.75 + m = 3.172144385 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + m = 3.172144385 + -3.75 m = 3.172144385 + -3.75 Combine like terms: 3.172144385 + -3.75 = -0.577855615 m = -0.577855615 Simplifying m = -0.577855615Subproblem 2
m + 3.75 = -3.172144385 Simplifying m + 3.75 = -3.172144385 Reorder the terms: 3.75 + m = -3.172144385 Solving 3.75 + m = -3.172144385 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-3.75' to each side of the equation. 3.75 + -3.75 + m = -3.172144385 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + m = -3.172144385 + -3.75 m = -3.172144385 + -3.75 Combine like terms: -3.172144385 + -3.75 = -6.922144385 m = -6.922144385 Simplifying m = -6.922144385Solution
