Simplifying 5m2 + 2m + -35 = 0 Reorder the terms: -35 + 2m + 5m2 = 0 Solving -35 + 2m + 5m2 = 0 Solving for variable 'm'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -7 + 0.4m + m2 = 0 Move the constant term to the right: Add '7' to each side of the equation. -7 + 0.4m + 7 + m2 = 0 + 7 Reorder the terms: -7 + 7 + 0.4m + m2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 0.4m + m2 = 0 + 7 0.4m + m2 = 0 + 7 Combine like terms: 0 + 7 = 7 0.4m + m2 = 7 The m term is 0.4m. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4m + 0.04 + m2 = 7 + 0.04 Reorder the terms: 0.04 + 0.4m + m2 = 7 + 0.04 Combine like terms: 7 + 0.04 = 7.04 0.04 + 0.4m + m2 = 7.04 Factor a perfect square on the left side: (m + 0.2)(m + 0.2) = 7.04 Calculate the square root of the right side: 2.653299832 Break this problem into two subproblems by setting (m + 0.2) equal to 2.653299832 and -2.653299832.Subproblem 1
m + 0.2 = 2.653299832 Simplifying m + 0.2 = 2.653299832 Reorder the terms: 0.2 + m = 2.653299832 Solving 0.2 + m = 2.653299832 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + m = 2.653299832 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + m = 2.653299832 + -0.2 m = 2.653299832 + -0.2 Combine like terms: 2.653299832 + -0.2 = 2.453299832 m = 2.453299832 Simplifying m = 2.453299832Subproblem 2
m + 0.2 = -2.653299832 Simplifying m + 0.2 = -2.653299832 Reorder the terms: 0.2 + m = -2.653299832 Solving 0.2 + m = -2.653299832 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + m = -2.653299832 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + m = -2.653299832 + -0.2 m = -2.653299832 + -0.2 Combine like terms: -2.653299832 + -0.2 = -2.853299832 m = -2.853299832 Simplifying m = -2.853299832Solution
