Oblicz :

a) (5x +4xy +5y) - (2x - xy - 3y) + (-x+2xy+y) =

b)-(2a + 3 ab) - (2b - ab) + (5a - 2ab) - (-5v+4ab) =

c) 92x -3) - (x^2 - 3x +1) + (3x ^ 2 - 6x -5) =

d) (0,5a ^2 +a) - (0,7a ^2 - 3a +1) - (-0,2^2 + 1,2a ^2 + 1,2a - 1,5) =

Z Obliczeniami Szybko potrzebuje na jutro DAJE NAJ KTO 1 Ten Lepszy ale dobrze ma byc!
