(4x^3-y^4)(3x+4x^8-9)

same method, we distribute term by term

\((4x^3-y^4)(3x+4x^8-9) \)

\((\color{green}{4x^3}-y^4)(\color{green}{3x+4x^8-9}) \)

I can't see equation using the buttons.

first distribute 3x^3, then \(-y^4\)

(4x^3-y^4)(3x+4x^8-9) is the equation.

hmm didnt get u

you put (3x^3) its (4x^3)

oh gotcha :)

okay.

yea distribute \(4x^3\) first

okay.

is it:
(12x^3+16x^11y^5-36x^3)?

I can't see the equations used from the buttons! please just type them! im totally confunsed. :/

oh you cant see the latex thats frustrating

all i see is \((\color{})(\color{}{}) \) but fulled with the equation

(4x^3 - y^4)(3x+4x^8-9)
4x^3(3x+4x^8-9) - y^4(3x+4x^8-9)

anyhoo, i have (12x^3+16x^11y^5-36x^3)

is that better

yea, thank you i can read it now! :)

4x^3(3x+4x^8-9) - y^4(3x+4x^8-9)
(12x^4 + 16x^11 - 36x^3) - (3xy^4 + 4x^8y^4 - 9y^4)

i have to condense my paper, give me a second.

(12x^4 + 16x^11 - 36x^3- 3xy^4 - 4x^8y^4 + 9y^4)

ok if u see any like terms, just add them. i think somthing went wrong in ur answer.. . check :)

for which part of the equation though?

i dont see any like terms. so thats it i hope

(12x^4 + 16x^11 - 36x^3- 3xy^4 - 4x^8y^4 + 9y^4)

12x^4 + 16x^11- 36x^3, 3xy^4 - 4x^8y^. are all like terms

why do u think they are like terms

they are all the same i.e. (x)^4,(x)^11,(-x)^3; (xy)^4,(x)^8(y)^4

(x)^4 and (x)^11 are not like terms

terms listed by you are satisfying first condition.
but they are failing second condition

|dw:1348066341953:dw|

|dw:1348066394415:dw|

hmm

How? |dw:1348066447218:dw|

|dw:1348066558698:dw|

first row you cannot add,
second row terms you can add

|dw:1348066611963:dw|

|dw:1348066641503:dw|

exponent must match, then only they are called like-terms, like-terms we can add

I don't get it though, lets see if we can get a mod in here to help me explain it.

ok

It's okay!

no. i fail epicly. its a fact of life

It's okay... When you don't fail again!

So, do you understand it now?

What about the 12x^3 and the -36^3? arn't they like terms?

wait, never mind. i fail......... AGAIN

They are the like terms, aren't they?

i forgot the the 4x^3*3x=12x^4 not ^3

Hi hartnn

Oh.. Just be careful next time :)

i will

practice and u will become good........

ik i will. Thanks.
