Simplifying m2 + -8m + -27 = 0 Reorder the terms: -27 + -8m + m2 = 0 Solving -27 + -8m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '27' to each side of the equation. -27 + -8m + 27 + m2 = 0 + 27 Reorder the terms: -27 + 27 + -8m + m2 = 0 + 27 Combine like terms: -27 + 27 = 0 0 + -8m + m2 = 0 + 27 -8m + m2 = 0 + 27 Combine like terms: 0 + 27 = 27 -8m + m2 = 27 The m term is -8m. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8m + 16 + m2 = 27 + 16 Reorder the terms: 16 + -8m + m2 = 27 + 16 Combine like terms: 27 + 16 = 43 16 + -8m + m2 = 43 Factor a perfect square on the left side: (m + -4)(m + -4) = 43 Calculate the square root of the right side: 6.557438524 Break this problem into two subproblems by setting (m + -4) equal to 6.557438524 and -6.557438524.Subproblem 1
m + -4 = 6.557438524 Simplifying m + -4 = 6.557438524 Reorder the terms: -4 + m = 6.557438524 Solving -4 + m = 6.557438524 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + m = 6.557438524 + 4 Combine like terms: -4 + 4 = 0 0 + m = 6.557438524 + 4 m = 6.557438524 + 4 Combine like terms: 6.557438524 + 4 = 10.557438524 m = 10.557438524 Simplifying m = 10.557438524Subproblem 2
