Simplifying x3 + 3x2 + -15x = 0 Reorder the terms: -15x + 3x2 + x3 = 0 Solving -15x + 3x2 + x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(-15 + 3x + x2) = 0Subproblem 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 '(-15 + 3x + x2)' equal to zero and attempt to solve: Simplifying -15 + 3x + x2 = 0 Solving -15 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '15' to each side of the equation. -15 + 3x + 15 + x2 = 0 + 15 Reorder the terms: -15 + 15 + 3x + x2 = 0 + 15 Combine like terms: -15 + 15 = 0 0 + 3x + x2 = 0 + 15 3x + x2 = 0 + 15 Combine like terms: 0 + 15 = 15 3x + x2 = 15 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 = 15 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 15 + 2.25 Combine like terms: 15 + 2.25 = 17.25 2.25 + 3x + x2 = 17.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 17.25 Calculate the square root of the right side: 4.153311931 Break this problem into two subproblems by setting (x + 1.5) equal to 4.153311931 and -4.153311931.Subproblem 1
x + 1.5 = 4.153311931 Simplifying x + 1.5 = 4.153311931 Reorder the terms: 1.5 + x = 4.153311931 Solving 1.5 + x = 4.153311931 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 = 4.153311931 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 4.153311931 + -1.5 x = 4.153311931 + -1.5 Combine like terms: 4.153311931 + -1.5 = 2.653311931 x = 2.653311931 Simplifying x = 2.653311931Subproblem 2
x + 1.5 = -4.153311931 Simplifying x + 1.5 = -4.153311931 Reorder the terms: 1.5 + x = -4.153311931 Solving 1.5 + x = -4.153311931 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 = -4.153311931 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -4.153311931 + -1.5 x = -4.153311931 + -1.5 Combine like terms: -4.153311931 + -1.5 = -5.653311931 x = -5.653311931 Simplifying x = -5.653311931Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.653311931, -5.653311931}Solution
x = {0, 2.653311931, -5.653311931}
