odpoveď:
# 2 / (x ^ 2-9) + 3 / (x ^ 2-4x + 3) = (5x + 7) / ((x-3), (x + 3) (x-1)) #
vysvetlenie:
# 2 / (x ^ 2-9) + 3 / (x ^ 2-4x + 3) #
= # 2 / ((x-3), (x + 3)) + 3 / ((x-3), (x-1)) #
= # (2 (x-1), 3 (x + 3)) / ((x-3), (x + 3) (x-1)) #
= # (2x-2 + 3 + 9) / ((x-3), (x + 3) (x-1)) #
= # (5x + 7) / ((x-3), (x + 3) (x-1)) #
