Simplifying -5x2 + -11x + 18 = 0 Reorder the terms: 18 + -11x + -5x2 = 0 Solving 18 + -11x + -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 + 2.2x + x2 = 0 Move the constant term to the right: Add '3.6' to each side of the equation. -3.6 + 2.2x + 3.6 + x2 = 0 + 3.6 Reorder the terms: -3.6 + 3.6 + 2.2x + x2 = 0 + 3.6 Combine like terms: -3.6 + 3.6 = 0.0 0.0 + 2.2x + x2 = 0 + 3.6 2.2x + x2 = 0 + 3.6 Combine like terms: 0 + 3.6 = 3.6 2.2x + x2 = 3.6 The x term is 2.2x. Take half its coefficient (1.1). Square it (1.21) and add it to both sides. Add '1.21' to each side of the equation. 2.2x + 1.21 + x2 = 3.6 + 1.21 Reorder the terms: 1.21 + 2.2x + x2 = 3.6 + 1.21 Combine like terms: 3.6 + 1.21 = 4.81 1.21 + 2.2x + x2 = 4.81 Factor a perfect square on the left side: (x + 1.1)(x + 1.1) = 4.81 Calculate the square root of the right side: 2.19317122 Break this problem into two subproblems by setting (x + 1.1) equal to 2.19317122 and -2.19317122.Subproblem 1
x + 1.1 = 2.19317122 Simplifying x + 1.1 = 2.19317122 Reorder the terms: 1.1 + x = 2.19317122 Solving 1.1 + x = 2.19317122 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.1' to each side of the equation. 1.1 + -1.1 + x = 2.19317122 + -1.1 Combine like terms: 1.1 + -1.1 = 0.0 0.0 + x = 2.19317122 + -1.1 x = 2.19317122 + -1.1 Combine like terms: 2.19317122 + -1.1 = 1.09317122 x = 1.09317122 Simplifying x = 1.09317122Subproblem 2
x + 1.1 = -2.19317122 Simplifying x + 1.1 = -2.19317122 Reorder the terms: 1.1 + x = -2.19317122 Solving 1.1 + x = -2.19317122 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.1' to each side of the equation. 1.1 + -1.1 + x = -2.19317122 + -1.1 Combine like terms: 1.1 + -1.1 = 0.0 0.0 + x = -2.19317122 + -1.1 x = -2.19317122 + -1.1 Combine like terms: -2.19317122 + -1.1 = -3.29317122 x = -3.29317122 Simplifying x = -3.29317122Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.09317122, -3.29317122}
