Simplifying (x2 + -1y2)(x2 + y2) = 175 Multiply (x2 + -1y2) * (x2 + y2) (x2(x2 + y2) + -1y2 * (x2 + y2)) = 175 ((x2 * x2 + y2 * x2) + -1y2 * (x2 + y2)) = 175 Reorder the terms: ((x2y2 + x4) + -1y2 * (x2 + y2)) = 175 ((x2y2 + x4) + -1y2 * (x2 + y2)) = 175 (x2y2 + x4 + (x2 * -1y2 + y2 * -1y2)) = 175 (x2y2 + x4 + (-1x2y2 + -1y4)) = 175 Reorder the terms: (x2y2 + -1x2y2 + x4 + -1y4) = 175 Combine like terms: x2y2 + -1x2y2 = 0 (0 + x4 + -1y4) = 175 (x4 + -1y4) = 175 Solving x4 + -1y4 = 175 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'y4' to each side of the equation. x4 + -1y4 + y4 = 175 + y4 Combine like terms: -1y4 + y4 = 0 x4 + 0 = 175 + y4 x4 = 175 + y4 Simplifying x4 = 175 + y4 Reorder the terms: -175 + x4 + -1y4 = 175 + y4 + -175 + -1y4 Reorder the terms: -175 + x4 + -1y4 = 175 + -175 + y4 + -1y4 Combine like terms: 175 + -175 = 0 -175 + x4 + -1y4 = 0 + y4 + -1y4 -175 + x4 + -1y4 = y4 + -1y4 Combine like terms: y4 + -1y4 = 0 -175 + x4 + -1y4 = 0 The solution to this equation could not be determined.
