Simplifying x6 + -4x5 + 13x4 = 0 Reorder the terms: 13x4 + -4x5 + x6 = 0 Solving 13x4 + -4x5 + x6 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x4'. x4(13 + -4x + x2) = 0Subproblem 1
Set the factor 'x4' equal to zero and attempt to solve: Simplifying x4 = 0 Solving x4 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x4 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(13 + -4x + x2)' equal to zero and attempt to solve: Simplifying 13 + -4x + x2 = 0 Solving 13 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + -4x + -13 + x2 = 0 + -13 Reorder the terms: 13 + -13 + -4x + x2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -4x + x2 = 0 + -13 -4x + x2 = 0 + -13 Combine like terms: 0 + -13 = -13 -4x + x2 = -13 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = -13 + 4 Reorder the terms: 4 + -4x + x2 = -13 + 4 Combine like terms: -13 + 4 = -9 4 + -4x + x2 = -9 Factor a perfect square on the left side: (x + -2)(x + -2) = -9 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
