Question

hi who can help me

Answer 1

with?

Answer 2

Find the first terms of the product in ascending powers.

(1-2x^2-x^4)(4+x^2-2x^4)

Answer 3

i know u helped me before but i am stuck

Answer 4

please somone help me

Answer 5

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

Answer 6

no this is a diffeent one and i am stuck

Answer 7

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

Answer 8

1-4+x^2+x^4

Answer 9

is it right

Answer 10

can u help me

Answer 11

please

Answer 12

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

Answer 13

LOL I THOUGHT THE SAMMEEE THING

Answer 21

yes. use khan academy

Answer 22

do you understand algebra?

Answer 23

yes

Answer 24

but not really

Answer 25

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

Answer 26

yes

Answer 27

well

Answer 28

well hello

Answer 29

then do you understand that
\[(1-2x ^{2}-x ^{4})(4+x ^{2}-2x ^{4})\]

is equal to
\[(1 \times 4 +1 \times x ^{2}-1 \times 2x ^{2}) -(2x ^{2} \times4+2x ^{2}\times x ^{2}-2x ^{2}\times 2x ^{4})\]
\[-(x ^{4}\times 4 +x ^{4} \times x ^{2}-x ^{4}\times 2x ^{4})\]

?

Answer 30

yes

Answer 31

ok

Answer 32

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

Answer 33

i am sorry, the first term in the equation i posted has -1 times 2x^2 in the end, it is supposed to be -1 times 2x^4

Answer 34

-5+x^2-7x^2

Answer 35

i guess is it right

Answer 36

no its not

Answer 37

where did you get -5 from?

Answer 38

oops sorry 4

Answer 39

help me

Answer 40

please

Answer 41

yes 4 is the first one.

Answer 42

-7x^2 is also correct

Answer 43

your answer is wrong. -5+x^2-7x^2 cannot be the answer. where did you get x^2-7x^2 from? isn't that just -6x^2?

Answer 44

so what is the answer

Answer 45

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

Answer 46

is it right can u hel p

Answer 47

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

Answer 48

that is not the answer.

Answer 49

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

Answer 50

instead of guessing the answer like this?

Answer 51

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

Answer 52

is it right
if not can u help me

Answer 53

what do you mean by 6 x^23?

Answer 54

sorry 6x^2

Answer 55

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

Answer 56

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

Answer 57

didnt i do that

Answer 58

no you did not.

Answer 59

i dont know what u mean

Answer 60

can u explain

Answer 61

is it that hard to multiply 4 times 1?

Answer 62

4

Answer 63

right. so scroll up. and do all the multiplications I showed you in my expression and post your answer. then we will figure out the answer together.

Answer 64

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

Answer 65

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

Answer 66

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

Answer 67

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

Answer 68

ok i got it

Answer 69

canu just write down the second equation for me i see it but can u do that for me so i can copy and paste

Answer 70

no.

Answer 71

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

Answer 72

is it right

Answer 73

and can u not be rue

Answer 74

rude

Answer 75

is it right

Answer 76

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

Answer 77

a^4

Answer 78

(2x^2×4+2x^2×x^2−2x^2×2x^4) = ?

Answer 79

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

Answer 80

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

Answer 81

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

Answer 82

is it right

Answer 83

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

Answer 84

-4x^6

Answer 85

right

Answer 86

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

Answer 87

(x^4×4+x^4×x^2−x^4×2x^4) = ?

Answer 88

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

Answer 89

is it right

Answer 90

yes. that is right.

Answer 91

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

Answer 92

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

Answer 93

is it right

Answer 94

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

Answer 95

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

Answer 96

is it right

Answer 97

those are the first three terms in ascending powers of x

Answer 98

so yes, that is your answer. bye
