Find the first terms of the product in ascending powers.
(1-2x^2-x^4)(4+x^2-2x^4)

i know u helped me before but i am stuck

please somone help me

oh ive already done this for you in detail. i dont understand why you keep reposting this.

no this is a diffeent one and i am stuck

(a+b)(c+d) = ac+ad+bc+bd.
similarly expand your problem and post what you get

1-4+x^2+x^4

is it right

can u help me

please

hold on. stop spamming. let me read what you posted,

LOL I THOUGHT THE SAMMEEE THING

what

no that is wrong, toxic

ok
can u help me further
Ill repay you

repay me with what?

nm

can u help me please?

or can u tell me a wesite that provides free online tutoring

yes. use khan academy

do you understand algebra?

yes

but not really

okay. then you understand that (a+b)(c-d) = ac -ad +bc - bd
?

yes

well

well hello

yes

ok

can you add all the x terms and x^2 terms and so on and post it here?

-5+x^2-7x^2

i guess is it right

no its not

where did you get -5 from?

oops sorry 4

help me

please

yes 4 is the first one.

-7x^2 is also correct

so what is the answer

is it 4-7x^2-6x^2

is it right can u hel p

why do you have a -6x^2 there? -7x^2 - 6x^2 = -13x^2

that is not the answer.

can you just use the expansion I gave you and write out fully what you would get?

instead of guessing the answer like this?

ok i got 4-7x^2-6x^23

is it right
if not can u help me

what do you mean by 6 x^23?

sorry 6x^2

I am not gonna help you until you write down and expand the expression I gave you.

that is the only way you will get the answer. you are just guessing the answer here.

didnt i do that

no you did not.

i dont know what u mean

can u explain

is it that hard to multiply 4 times 1?

(1×4+1×x^2−1×2x^4) = (4 +x^2 -2x^4)
similarly write down the other two separately and post them here

i am sorry for being diffuct but i dont get what u said

then you shouldn't take math. Sorry I cannot help you any more.

take my advice and drop math. its not your strong suit

ok i got it

no.

ok i got -4x^2+2x^4+8x^2

is it right

and can u not be rue

rude

is it right

no it is not.
do you know what a^2 times a^2 =?

a^4

(2x^2×4+2x^2×x^2−2x^2×2x^4) = ?

(2x^2×4+2x^2×x^2−2x^2×2x^4) = ( (2x^2×4) + (2x^2×x^2) − (2x^2×2x^4) )

now multiply the individual products within each brackets and write down the answer

8x^2+2x^4-4x^6

is it right

yes thats right. now do the last one too and post your answer

-4x^6

right

no i meant the third expression in the big expression I gave you

(x^4×4+x^4×x^2−x^4×2x^4) = ?

ok i got -2x^8+x^6+4x^4

is it right

yes. that is right.

so now do (4 +x^2 -2x^4) - (8x^2+2x^4-4x^6) - (-2x^8+x^6+4x^4) and post your answer

ok i got -8x^4-7x^2+4+3x^6-2x^8

is it right

yes thats right. now just write this expression in ascending powers.

ok 4-7x^2-8x^4

is it right

those are the first three terms in ascending powers of x

so yes, that is your answer. bye
