well, why don't you multiply the two polynomials and post what you got?

ok

i got 4-x^2-2x^4-8x^4x^6-4x^4-x^6-2x^8
is that right and if it isnt caould you please correct me

there should be a plus of minus sign between 8x^4 and x^6 in the polynomial you posted

so my answer is not right

ohh i see there is a minus between 8x^4 and x^6

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

and so on. so group all the terms together and write down your expression

i dont know but i got 4-x^2-14x^4-2x^6-2x^8

is that right

is it 4-x^2-14x^4

yes.

ok thanks you

cana you help me with on more promblem

although you should say, the first three terms are
4, -x^2 and -14x^4

you are welcome. post your other problem and we will see how to solve it.

do u get it
or no

ok srry not that one

yes, i got it. do you want the answer or not?

yes

thanks

okay it says the box is 3 feet longer than its width.
so length = ?

i dont know can u show me the firt time please

can u help me please

if width is w, length = w + 3feet.

so if height is 2 feet less than width,
height = ?

2-w

or w-2

yes, w -2 is correct.
so width is w, length is w+3 and height is w-2

what is the volume and surface area then?

im not sure
surface area is( w-2)(w+3)

can u help me

what is the volume of a cuboid?

just tell me the general formula.

ok
the surface formula

http://www.gcsemathstutor.com/images/shapespace/ss-vol-cuboid.jpg

http://www.mathsteacher.com.au/year10/ch14_measurement/14_cuboid/20cuboid.htm

s=2lh+2wh+2lw

is that it

yes. so express the surface area in terms of the height width and length of your cube.

so do i plug in the 3 and 2 for the height and the width

your height is w -2
and length is w+3
and width is w.
so plug those values.

so s=2(w+3)(w-2)+2(w)(w-2)+2(w+3)(w)

is it right

yes

now do i distrubuite

yes, you can do that

how do i muliply 2(w+3)(w-2)

can you just show me

http://www.webmath.com/polymult.html

ok i got 6w^2+4w-12
is that right

is it right

no

than can u help me

please

i gave you the link, did you use it?

yes ill do it again

okay.

igot the same thing

unless im doing something wrong

r u there

yes, \[2(w+3)(w-2)=2(w \times w +3 \times w -2 \times w -2 \times 3)\]

\[= 2(w ^{2}+w-6)=2w ^{2}+2w-12\]

is that it

is that the anwer to that question

no, that is the multiplication of 2(w+3)(w-2)
the surface area is 2 lw+2lh+2hw
and the volume is lwh

ok can u help me step by step please

im so lost

can u help

what do you need help with? I already explained everything to you.

no answering the suface area

please like how do u solve 2(w+3)(w-2)+2(w)(w-2)+2(w+3)(w)

2w(w-2) = 2w^2-4w
2w(w+3) = 2w^2+6w.
2(w+3)(w-2) = 2w^2 +2w-12
add all three and post what you get.

6w^4w-12 is that right

is it

please help me

r u there

yes that is right. that is the surface area.

ok and the volume of the box

the surface area of the the box is 6w^6+4w-12

how did you get 6w^6 term in there?

i dk

can you add the three terms like I said and post it here properly?

i did

2w(w-2) = 2w^2-4w
2w(w+3) = 2w^2+6w.
2(w+3)(w-2) = 2w^2 +2w-12
add all three and post what you get

that is what i got but i can doit again

so how did you get a w^6 term there if you added them properly?

2w^2-4w
2w^2+6w.
2w^2 +2w-1=6w^6+4w-12

okay, you added 2w^2+2w^2+2w^2 and got 6w^6?

can u help me please

you added -4w+6w+2w and got 4w correct?

ohh yes so can u write the answer again please

you get 4 what?

oranges

okay
so if you add two w squares to two w squares, how many w squares do you get?

4 w

6w

okay, so what is 2w^2+2w^2+2w^2?

6w

can u just show me

okay. 2 w^2 +2w^2+2w^2 = 6 w^2, not 6w^6

do you understand?

ok thanks

w^2 is the same as w times w.

i understand

can u help me with the volume now
