Simplifying x3 + 3x2 + -35x = 0 Reorder the terms: -35x + 3x2 + x3 = 0 Solving -35x + 3x2 + x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(-35 + 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 '(-35 + 3x + x2)' equal to zero and attempt to solve: Simplifying -35 + 3x + x2 = 0 Solving -35 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '35' to each side of the equation. -35 + 3x + 35 + x2 = 0 + 35 Reorder the terms: -35 + 35 + 3x + x2 = 0 + 35 Combine like terms: -35 + 35 = 0 0 + 3x + x2 = 0 + 35 3x + x2 = 0 + 35 Combine like terms: 0 + 35 = 35 3x + x2 = 35 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 = 35 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 35 + 2.25 Combine like terms: 35 + 2.25 = 37.25 2.25 + 3x + x2 = 37.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 37.25 Calculate the square root of the right side: 6.103277808 Break this problem into two subproblems by setting (x + 1.5) equal to 6.103277808 and -6.103277808.Subproblem 1
x + 1.5 = 6.103277808 Simplifying x + 1.5 = 6.103277808 Reorder the terms: 1.5 + x = 6.103277808 Solving 1.5 + x = 6.103277808 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 = 6.103277808 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 6.103277808 + -1.5 x = 6.103277808 + -1.5 Combine like terms: 6.103277808 + -1.5 = 4.603277808 x = 4.603277808 Simplifying x = 4.603277808Subproblem 2
x + 1.5 = -6.103277808 Simplifying x + 1.5 = -6.103277808 Reorder the terms: 1.5 + x = -6.103277808 Solving 1.5 + x = -6.103277808 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 = -6.103277808 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -6.103277808 + -1.5 x = -6.103277808 + -1.5 Combine like terms: -6.103277808 + -1.5 = -7.603277808 x = -7.603277808 Simplifying x = -7.603277808Solution
