Question

reduza o monomios semelhantes: b)4a²-10a²-6a²-4a². c)15y-10y-6y d)-¾ax-⅓ax-½ax

Answer 1

b)4a²-10a²-6a²-4a²

2a²(2 -5 -3 -2)

2a² (2 -10) =

2a² (-8)

...

c)15y-10y-6y

y(15 -10 -6) =

y (15 -16) =

y (-1)

...

d)-¾ax-⅓ax-½ax =

ax(-3/4 -1/3 -1/2) = mmc = 12

ax(-12:4.3 -12:3.1 -12:2.1) =

ax(-9 -4 -6) =

ax(-19)
