Question

Simplify.

−1w + 4w4 + y4 – 3y4 – 2w – 3w4

A.
−2w4 – 2y4

B.
−w4y4 – 3w

C.
w4 – 3w – 2y4

D.
12w4 + 2w – 3y4

Answer 1

please you have to sum similar monomials

Answer 2

(-1w+2w)+(4w4-3w4)-(y4_3y4) is this right?

Answer 3

that's right!

Answer 4

please first parenthesis is -1w-2w

Answer 5

I got 1w+1w4-3y4

Answer 6

sorry , I got another answer,

Answer 7

Can you tell me how you got another answer?

Answer 8

don't worry, now first term is -1w-2w, are you agree?

Answer 9

yes

Answer 10

ok!, second term is right, namely 4w^4-3w^4

Answer 11

third term is -(3y^4-y^4) are you agree?

Answer 12

yes

Answer 13

ok! so retry please

Answer 14

how do you add and subtract them together?

Answer 15

for example -1w-2w=-3w, because -1+(-2)=-3

Answer 16

literal parts is the same, you have only to add the numerical parts each other, in order to add similar monomials

Answer 17

is it clear?

Answer 18

Not really

Answer 19

another example: -3x+5x=2x, because the literal part is the common literal part, namely x, whereas the coefficient is 2, because -3+5=2, so 2x

Answer 20

So its between b and c

Answer 21

please let us continue as before, the first term is -3w, are you agree?

Answer 22

yes

Answer 23

ok!, the second term is 4w^4-3w^4=w^4, are you agree?

Answer 24

I thought it was 1w4

Answer 25

yes it the same thing, in general when the coefficient is 1, you can omit it

Answer 26

ok

Answer 27

now the third term is -(3y^4-y^4)=-(2y^4)=-2y^4, are you agree?

Answer 28

yes

Answer 29

perfect, now you have to sum these three terms:
-3w;
w^4
-2y^4
note that they are not similar monomials, so whe we add them each other, we can only write them one near to other, so?

Answer 30

so its c

Answer 31

well done!, that's right!

Answer 32

Thank you. You were alot of help

Answer 33

Thank you!
