Simplifying 4m2 + 7m = 6 Reorder the terms: 7m + 4m2 = 6 Solving 7m + 4m2 = 6 Solving for variable 'm'. Reorder the terms: -6 + 7m + 4m2 = 6 + -6 Combine like terms: 6 + -6 = 0 -6 + 7m + 4m2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1.5 + 1.75m + m2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + 1.75m + 1.5 + m2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + 1.75m + m2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + 1.75m + m2 = 0 + 1.5 1.75m + m2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 1.75m + m2 = 1.5 The m term is 1.75m. Take half its coefficient (0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. 1.75m + 0.765625 + m2 = 1.5 + 0.765625 Reorder the terms: 0.765625 + 1.75m + m2 = 1.5 + 0.765625 Combine like terms: 1.5 + 0.765625 = 2.265625 0.765625 + 1.75m + m2 = 2.265625 Factor a perfect square on the left side: (m + 0.875)(m + 0.875) = 2.265625 Calculate the square root of the right side: 1.505199322 Break this problem into two subproblems by setting (m + 0.875) equal to 1.505199322 and -1.505199322.Subproblem 1
m + 0.875 = 1.505199322 Simplifying m + 0.875 = 1.505199322 Reorder the terms: 0.875 + m = 1.505199322 Solving 0.875 + m = 1.505199322 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.875' to each side of the equation. 0.875 + -0.875 + m = 1.505199322 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + m = 1.505199322 + -0.875 m = 1.505199322 + -0.875 Combine like terms: 1.505199322 + -0.875 = 0.630199322 m = 0.630199322 Simplifying m = 0.630199322Subproblem 2
m + 0.875 = -1.505199322 Simplifying m + 0.875 = -1.505199322 Reorder the terms: 0.875 + m = -1.505199322 Solving 0.875 + m = -1.505199322 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.875' to each side of the equation. 0.875 + -0.875 + m = -1.505199322 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + m = -1.505199322 + -0.875 m = -1.505199322 + -0.875 Combine like terms: -1.505199322 + -0.875 = -2.380199322 m = -2.380199322 Simplifying m = -2.380199322Solution
