Simplifying 4x3 + 34x2 + 44x = 0 Reorder the terms: 44x + 34x2 + 4x3 = 0 Solving 44x + 34x2 + 4x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x'. 2x(22 + 17x + 2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(22 + 17x + 2x2)' equal to zero and attempt to solve: Simplifying 22 + 17x + 2x2 = 0 Solving 22 + 17x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 11 + 8.5x + x2 = 0 Move the constant term to the right: Add '-11' to each side of the equation. 11 + 8.5x + -11 + x2 = 0 + -11 Reorder the terms: 11 + -11 + 8.5x + x2 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + 8.5x + x2 = 0 + -11 8.5x + x2 = 0 + -11 Combine like terms: 0 + -11 = -11 8.5x + x2 = -11 The x term is 8.5x. Take half its coefficient (4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. 8.5x + 18.0625 + x2 = -11 + 18.0625 Reorder the terms: 18.0625 + 8.5x + x2 = -11 + 18.0625 Combine like terms: -11 + 18.0625 = 7.0625 18.0625 + 8.5x + x2 = 7.0625 Factor a perfect square on the left side: (x + 4.25)(x + 4.25) = 7.0625 Calculate the square root of the right side: 2.657536453 Break this problem into two subproblems by setting (x + 4.25) equal to 2.657536453 and -2.657536453.Subproblem 1
x + 4.25 = 2.657536453 Simplifying x + 4.25 = 2.657536453 Reorder the terms: 4.25 + x = 2.657536453 Solving 4.25 + x = 2.657536453 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + x = 2.657536453 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = 2.657536453 + -4.25 x = 2.657536453 + -4.25 Combine like terms: 2.657536453 + -4.25 = -1.592463547 x = -1.592463547 Simplifying x = -1.592463547Subproblem 2
x + 4.25 = -2.657536453 Simplifying x + 4.25 = -2.657536453 Reorder the terms: 4.25 + x = -2.657536453 Solving 4.25 + x = -2.657536453 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + x = -2.657536453 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = -2.657536453 + -4.25 x = -2.657536453 + -4.25 Combine like terms: -2.657536453 + -4.25 = -6.907536453 x = -6.907536453 Simplifying x = -6.907536453Solution
