Simplifying 2x2 + 6x + -864 = 0 Reorder the terms: -864 + 6x + 2x2 = 0 Solving -864 + 6x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-432 + 3x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-432 + 3x + x2)' equal to zero and attempt to solve: Simplifying -432 + 3x + x2 = 0 Solving -432 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '432' to each side of the equation. -432 + 3x + 432 + x2 = 0 + 432 Reorder the terms: -432 + 432 + 3x + x2 = 0 + 432 Combine like terms: -432 + 432 = 0 0 + 3x + x2 = 0 + 432 3x + x2 = 0 + 432 Combine like terms: 0 + 432 = 432 3x + x2 = 432 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 432 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 432 + 2.25 Combine like terms: 432 + 2.25 = 434.25 2.25 + 3x + x2 = 434.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 434.25 Calculate the square root of the right side: 20.838665984 Break this problem into two subproblems by setting (x + 1.5) equal to 20.838665984 and -20.838665984.Subproblem 1
x + 1.5 = 20.838665984 Simplifying x + 1.5 = 20.838665984 Reorder the terms: 1.5 + x = 20.838665984 Solving 1.5 + x = 20.838665984 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 20.838665984 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 20.838665984 + -1.5 x = 20.838665984 + -1.5 Combine like terms: 20.838665984 + -1.5 = 19.338665984 x = 19.338665984 Simplifying x = 19.338665984Subproblem 2
x + 1.5 = -20.838665984 Simplifying x + 1.5 = -20.838665984 Reorder the terms: 1.5 + x = -20.838665984 Solving 1.5 + x = -20.838665984 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -20.838665984 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -20.838665984 + -1.5 x = -20.838665984 + -1.5 Combine like terms: -20.838665984 + -1.5 = -22.338665984 x = -22.338665984 Simplifying x = -22.338665984Solution
The solution to the problem is based on the solutions from the subproblems. x = {19.338665984, -22.338665984}Solution
x = {19.338665984, -22.338665984}
