Obrazloženje:
# A * (ax + by) + b * (bx-ay) = a * (a-b) + b * (a-b) #
# A ^ 2 * X + aby + b ^ 2 * X-aby = a ^ 2-ab + ab-b ^ 2 #
# (A + b ^ 2 ^ 2) + x = a ^ 2-b ^ 2 #
# X = (a ^ 2-b ^ 2) / (a + b ^ 2 ^ 2) *
Tako, # A * (a ^ 2-b ^ 2) / (a + b ^ 2 ^ 2) + s = a-b #
# A * (a ^ 2-b ^ 2) + * od (a + b ^ 2 ^ 2) = (a-b) + (a + b ^ 2 ^ 2) *
# A ^ 3-ab ^ 2 + (a + b ^ 2 ^ 2) + s = ^ 3 + ab ^ 2-a ^ 2 * b-b ^ 3 #
# (A + b ^ 2 ^ 2) * = po 2ab ^ 2-a ^ 2 * b-b ^ 3 #
# Y = (2ab ^ 2-a ^ 2 * b-b ^ 3) / b * (a + b ^ 2 ^ 2) #
=# (2ab-a ^ 2-b ^ 2) / (a + b ^ 2 ^ 2) *
