Resposta:
a)3ax + 5bx - 12ax - 15bx + 4x =
3ax - 12ax + 5bx - 15bx + 4x =
-9ax -10bx + 4x =
x(-9a -10b + 4)
b)15−4+3+12−20
27−4+3−20
3+27−24
C) 24aw+6x-12aw-6x= (24aw-12aw)+(6x-6x)=12aw+0=12aw.
d) : 15ax + 6ax = 21ax
e) m.m.c(6,2)=6
>>3by + 15by/6
>>18by/6
>>3by
f) 32cz^3 + 24 cx^3
>>56cz^3
g) (– 102 + 202) . ax2 = + 100ax2
h) 12by – 7by = 5by
i) -34x²+5y³
j) = 2,7x2
Espero ter ajudado!
