Simplifying 5x2 + 27x + 18 = 0 Reorder the terms: 18 + 27x + 5x2 = 0 Solving 18 + 27x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 3.6 + 5.4x + x2 = 0 Move the constant term to the right: Add '-3.6' to each side of the equation. 3.6 + 5.4x + -3.6 + x2 = 0 + -3.6 Reorder the terms: 3.6 + -3.6 + 5.4x + x2 = 0 + -3.6 Combine like terms: 3.6 + -3.6 = 0.0 0.0 + 5.4x + x2 = 0 + -3.6 5.4x + x2 = 0 + -3.6 Combine like terms: 0 + -3.6 = -3.6 5.4x + x2 = -3.6 The x term is 5.4x. Take half its coefficient (2.7). Square it (7.29) and add it to both sides. Add '7.29' to each side of the equation. 5.4x + 7.29 + x2 = -3.6 + 7.29 Reorder the terms: 7.29 + 5.4x + x2 = -3.6 + 7.29 Combine like terms: -3.6 + 7.29 = 3.69 7.29 + 5.4x + x2 = 3.69 Factor a perfect square on the left side: (x + 2.7)(x + 2.7) = 3.69 Calculate the square root of the right side: 1.920937271 Break this problem into two subproblems by setting (x + 2.7) equal to 1.920937271 and -1.920937271.Subproblem 1
x + 2.7 = 1.920937271 Simplifying x + 2.7 = 1.920937271 Reorder the terms: 2.7 + x = 1.920937271 Solving 2.7 + x = 1.920937271 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.7' to each side of the equation. 2.7 + -2.7 + x = 1.920937271 + -2.7 Combine like terms: 2.7 + -2.7 = 0.0 0.0 + x = 1.920937271 + -2.7 x = 1.920937271 + -2.7 Combine like terms: 1.920937271 + -2.7 = -0.779062729 x = -0.779062729 Simplifying x = -0.779062729Subproblem 2
x + 2.7 = -1.920937271 Simplifying x + 2.7 = -1.920937271 Reorder the terms: 2.7 + x = -1.920937271 Solving 2.7 + x = -1.920937271 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.7' to each side of the equation. 2.7 + -2.7 + x = -1.920937271 + -2.7 Combine like terms: 2.7 + -2.7 = 0.0 0.0 + x = -1.920937271 + -2.7 x = -1.920937271 + -2.7 Combine like terms: -1.920937271 + -2.7 = -4.620937271 x = -4.620937271 Simplifying x = -4.620937271Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.779062729, -4.620937271}
