Simplifying 20x2 + 11x + -48 = 0 Reorder the terms: -48 + 11x + 20x2 = 0 Solving -48 + 11x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -2.4 + 0.55x + x2 = 0 Move the constant term to the right: Add '2.4' to each side of the equation. -2.4 + 0.55x + 2.4 + x2 = 0 + 2.4 Reorder the terms: -2.4 + 2.4 + 0.55x + x2 = 0 + 2.4 Combine like terms: -2.4 + 2.4 = 0.0 0.0 + 0.55x + x2 = 0 + 2.4 0.55x + x2 = 0 + 2.4 Combine like terms: 0 + 2.4 = 2.4 0.55x + x2 = 2.4 The x term is 0.55x. Take half its coefficient (0.275). Square it (0.075625) and add it to both sides. Add '0.075625' to each side of the equation. 0.55x + 0.075625 + x2 = 2.4 + 0.075625 Reorder the terms: 0.075625 + 0.55x + x2 = 2.4 + 0.075625 Combine like terms: 2.4 + 0.075625 = 2.475625 0.075625 + 0.55x + x2 = 2.475625 Factor a perfect square on the left side: (x + 0.275)(x + 0.275) = 2.475625 Calculate the square root of the right side: 1.573411898 Break this problem into two subproblems by setting (x + 0.275) equal to 1.573411898 and -1.573411898.Subproblem 1
x + 0.275 = 1.573411898 Simplifying x + 0.275 = 1.573411898 Reorder the terms: 0.275 + x = 1.573411898 Solving 0.275 + x = 1.573411898 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.275' to each side of the equation. 0.275 + -0.275 + x = 1.573411898 + -0.275 Combine like terms: 0.275 + -0.275 = 0.000 0.000 + x = 1.573411898 + -0.275 x = 1.573411898 + -0.275 Combine like terms: 1.573411898 + -0.275 = 1.298411898 x = 1.298411898 Simplifying x = 1.298411898Subproblem 2
x + 0.275 = -1.573411898 Simplifying x + 0.275 = -1.573411898 Reorder the terms: 0.275 + x = -1.573411898 Solving 0.275 + x = -1.573411898 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.275' to each side of the equation. 0.275 + -0.275 + x = -1.573411898 + -0.275 Combine like terms: 0.275 + -0.275 = 0.000 0.000 + x = -1.573411898 + -0.275 x = -1.573411898 + -0.275 Combine like terms: -1.573411898 + -0.275 = -1.848411898 x = -1.848411898 Simplifying x = -1.848411898Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.298411898, -1.848411898}
