Simplifying x(2x + 4) = 80 Reorder the terms: x(4 + 2x) = 80 (4 * x + 2x * x) = 80 (4x + 2x2) = 80 Solving 4x + 2x2 = 80 Solving for variable 'x'. Reorder the terms: -80 + 4x + 2x2 = 80 + -80 Combine like terms: 80 + -80 = 0 -80 + 4x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-40 + 2x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-40 + 2x + x2)' equal to zero and attempt to solve: Simplifying -40 + 2x + x2 = 0 Solving -40 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '40' to each side of the equation. -40 + 2x + 40 + x2 = 0 + 40 Reorder the terms: -40 + 40 + 2x + x2 = 0 + 40 Combine like terms: -40 + 40 = 0 0 + 2x + x2 = 0 + 40 2x + x2 = 0 + 40 Combine like terms: 0 + 40 = 40 2x + x2 = 40 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 40 + 1 Reorder the terms: 1 + 2x + x2 = 40 + 1 Combine like terms: 40 + 1 = 41 1 + 2x + x2 = 41 Factor a perfect square on the left side: (x + 1)(x + 1) = 41 Calculate the square root of the right side: 6.403124237 Break this problem into two subproblems by setting (x + 1) equal to 6.403124237 and -6.403124237.Subproblem 1
x + 1 = 6.403124237 Simplifying x + 1 = 6.403124237 Reorder the terms: 1 + x = 6.403124237 Solving 1 + x = 6.403124237 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 6.403124237 + -1 Combine like terms: 1 + -1 = 0 0 + x = 6.403124237 + -1 x = 6.403124237 + -1 Combine like terms: 6.403124237 + -1 = 5.403124237 x = 5.403124237 Simplifying x = 5.403124237Subproblem 2
x + 1 = -6.403124237 Simplifying x + 1 = -6.403124237 Reorder the terms: 1 + x = -6.403124237 Solving 1 + x = -6.403124237 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -6.403124237 + -1 Combine like terms: 1 + -1 = 0 0 + x = -6.403124237 + -1 x = -6.403124237 + -1 Combine like terms: -6.403124237 + -1 = -7.403124237 x = -7.403124237 Simplifying x = -7.403124237Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.403124237, -7.403124237}Solution
x = {5.403124237, -7.403124237}
