1. Wykonaj działania :
a) 6(x-4)- 2=
b) 2(x+1)- 3(x+1)=
c) -3(y-2) + 4(y+2) =
d) 5(x-y-1) - 4(x+2)=
e) 2(3a + b) - 2(a- b )=
f) ½(4x - 4) - 2x =
g) x(x-1) - 3(x² - x)=
h) 5a(a-3) - 3a(a-5)=
i) 3x(x+⅓ y ) - 2y (½x - ½)=

2.Uprość podane wyrażenie :
4 * (x-7) :2 + 9 * (x-1) : 3 =

z.3 Wyłącz wspólny czynnik przed nawias :
a) 5x + 10y =
b) 4m + 4 =
c) 3a- 3 =
d) 5xy - x =
e) -6a² - 2a =
f) 6a² - 12ab =
g) ½ xy - ½x =
h) ⅓ a²b + 1/9ab² =
i) 2xyz - 4x²y²z + xyz² =
j) stv² - stv + tv² =
* 1/9 = jedna dziewiąta
-----------
z. 4 Zapisz w postaci iloczynu :
a) ½ * 4(a+b) - ½h(a+b) =
b) z(x-y)-(y-x) =
PROSZE TO NA JUTRO . DAM NAJ :))
