Simplifying (x2 + y4)(x2 + -1y4) = 0 Multiply (x2 + y4) * (x2 + -1y4) (x2(x2 + -1y4) + y4(x2 + -1y4)) = 0 ((x2 * x2 + -1y4 * x2) + y4(x2 + -1y4)) = 0 Reorder the terms: ((-1x2y4 + x4) + y4(x2 + -1y4)) = 0 ((-1x2y4 + x4) + y4(x2 + -1y4)) = 0 (-1x2y4 + x4 + (x2 * y4 + -1y4 * y4)) = 0 (-1x2y4 + x4 + (x2y4 + -1y8)) = 0 Reorder the terms: (-1x2y4 + x2y4 + x4 + -1y8) = 0 Combine like terms: -1x2y4 + x2y4 = 0 (0 + x4 + -1y8) = 0 (x4 + -1y8) = 0 Solving x4 + -1y8 = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'y8' to each side of the equation. x4 + -1y8 + y8 = 0 + y8 Combine like terms: -1y8 + y8 = 0 x4 + 0 = 0 + y8 x4 = 0 + y8 Remove the zero: x4 = y8 Simplifying x4 = y8 Combine like terms: y8 + -1y8 = 0 x4 + -1y8 = 0 Factor a difference between two squares. (x2 + y4)(x2 + -1y4) = 0 Factor a difference between two squares. (x2 + y4)((x + y2)(x + -1y2)) = 0Subproblem 1
Set the factor '(x2 + y4)' equal to zero and attempt to solve: Simplifying x2 + y4 = 0 Solving x2 + y4 = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y4' to each side of the equation. x2 + y4 + -1y4 = 0 + -1y4 Combine like terms: y4 + -1y4 = 0 x2 + 0 = 0 + -1y4 x2 = 0 + -1y4 Remove the zero: x2 = -1y4 Simplifying x2 = -1y4 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 '(x + y2)' equal to zero and attempt to solve: Simplifying x + y2 = 0 Solving x + y2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y2' to each side of the equation. x + y2 + -1y2 = 0 + -1y2 Combine like terms: y2 + -1y2 = 0 x + 0 = 0 + -1y2 x = 0 + -1y2 Remove the zero: x = -1y2 Simplifying x = -1y2Subproblem 3
Set the factor '(x + -1y2)' equal to zero and attempt to solve: Simplifying x + -1y2 = 0 Solving x + -1y2 = 0 Move all terms containing x to the left, all other terms to the right. Add 'y2' to each side of the equation. x + -1y2 + y2 = 0 + y2 Combine like terms: -1y2 + y2 = 0 x + 0 = 0 + y2 x = 0 + y2 Remove the zero: x = y2 Simplifying x = y2Solution
x = {-1y2, y2}
