Simplifying -1x3 + -7x2 = x4 Reorder the terms: -7x2 + -1x3 = x4 Solving -7x2 + -1x3 = x4 Solving for variable 'x'. Combine like terms: x4 + -1x4 = 0 -7x2 + -1x3 + -1x4 = 0 Factor out the Greatest Common Factor (GCF), '-1x2'. -1x2(7 + x + x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor 'x2' equal to zero and attempt to solve: Simplifying x2 = 0 Solving x2 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x2 = 0 Take the square root of each side: x = {0}Subproblem 2
Set the factor '(7 + x + x2)' equal to zero and attempt to solve: Simplifying 7 + x + x2 = 0 Solving 7 + x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + x + -7 + x2 = 0 + -7 Reorder the terms: 7 + -7 + x + x2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + x + x2 = 0 + -7 x + x2 = 0 + -7 Combine like terms: 0 + -7 = -7 x + x2 = -7 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = -7 + 0.25 Reorder the terms: 0.25 + x + x2 = -7 + 0.25 Combine like terms: -7 + 0.25 = -6.75 0.25 + x + x2 = -6.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -6.75 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.Solution
x = {0}
