Simplifying 3x2 + 27x + -9.1 = 0 Reorder the terms: -9.1 + 27x + 3x2 = 0 Solving -9.1 + 27x + 3x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -3.033333333 + 9x + x2 = 0 Move the constant term to the right: Add '3.033333333' to each side of the equation. -3.033333333 + 9x + 3.033333333 + x2 = 0 + 3.033333333 Reorder the terms: -3.033333333 + 3.033333333 + 9x + x2 = 0 + 3.033333333 Combine like terms: -3.033333333 + 3.033333333 = 0.000000000 0.000000000 + 9x + x2 = 0 + 3.033333333 9x + x2 = 0 + 3.033333333 Combine like terms: 0 + 3.033333333 = 3.033333333 9x + x2 = 3.033333333 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = 3.033333333 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 3.033333333 + 20.25 Combine like terms: 3.033333333 + 20.25 = 23.283333333 20.25 + 9x + x2 = 23.283333333 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 23.283333333 Calculate the square root of the right side: 4.825280648 Break this problem into two subproblems by setting (x + 4.5) equal to 4.825280648 and -4.825280648.Subproblem 1
x + 4.5 = 4.825280648 Simplifying x + 4.5 = 4.825280648 Reorder the terms: 4.5 + x = 4.825280648 Solving 4.5 + x = 4.825280648 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 4.825280648 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 4.825280648 + -4.5 x = 4.825280648 + -4.5 Combine like terms: 4.825280648 + -4.5 = 0.325280648 x = 0.325280648 Simplifying x = 0.325280648Subproblem 2
x + 4.5 = -4.825280648 Simplifying x + 4.5 = -4.825280648 Reorder the terms: 4.5 + x = -4.825280648 Solving 4.5 + x = -4.825280648 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -4.825280648 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -4.825280648 + -4.5 x = -4.825280648 + -4.5 Combine like terms: -4.825280648 + -4.5 = -9.325280648 x = -9.325280648 Simplifying x = -9.325280648Solution
