Simplifying 2x4 + -2x2 + 70 = 0 Reorder the terms: 70 + -2x2 + 2x4 = 0 Solving 70 + -2x2 + 2x4 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(35 + -1x2 + x4) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(35 + -1x2 + x4)' equal to zero and attempt to solve: Simplifying 35 + -1x2 + x4 = 0 Solving 35 + -1x2 + x4 = 0 Begin completing the square. Move the constant term to the right: Add '-35' to each side of the equation. 35 + -1x2 + -35 + x4 = 0 + -35 Reorder the terms: 35 + -35 + -1x2 + x4 = 0 + -35 Combine like terms: 35 + -35 = 0 0 + -1x2 + x4 = 0 + -35 -1x2 + x4 = 0 + -35 Combine like terms: 0 + -35 = -35 -1x2 + x4 = -35 The x term is -1x2. 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. -1x2 + 0.25 + x4 = -35 + 0.25 Reorder the terms: 0.25 + -1x2 + x4 = -35 + 0.25 Combine like terms: -35 + 0.25 = -34.75 0.25 + -1x2 + x4 = -34.75 Factor a perfect square on the left side: (x2 + -0.5)(x2 + -0.5) = -34.75 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. The solution to this equation could not be determined.
