zad 1
a . = 3x do kwadratu - 21 x
b. = a do sześcianu + 2a kwadrat b - a kwadrat
c. = - 3 x kwadrat y - 3 x(y)kwadrat + 9xy
d. = 5x do szóstej potegi + 15 x do sześcianu - 5 x kwadrat
zad 2
a. = 3a +3b + a - 2b = 4a + b
b. = -4x +4z - x-y = -5x+4z-y
c. = 20x-35+7-4x= 16x-28 -4x
d. = 4x-y-2x-2y=2x-3y
e.= 6x-4y+6z-5x+5y+5z= x + y +11z
f. 4x kwadrat-4xy-4xz -8x kwadrat +2xy-2xz= -2xy-2xz-8xkwadrat
g. -3xsześcian + 2xkwadrat y +5x szescian - 35x kwadrat y = 2x szescian -33x kwadrat y
chyba tak :) ale nie jestem pewna :D
