Całe zadanie w załączniku. - nie brac z interetu :) prosiłbym o działania :-)
Pozdrawiam . i czekam .
(a²b+3ab²-ab)/2c=12
a)
(a²b+3ab²-ab)/4c= 1/2*(a²b+3ab²-ab)/2c= 1/2*12=6
b)
(2a²b+6ab²-2ab)/c=4*(a²b+3ab²-ab)/2c=4*12=48
c)
(3ab-3a²b-9ab²)/4c= -3/2*(-ab+a²b+3ab²)/2c=-3/2*(a²b+3ab²-ab)/2c=-3/2*12=-18
