= 26 :)

-16yx^2 + 128x^2 - 16y^2x + 128yx

= 26 :)


Can you explain how you got the answer please?:thumbsup:
suspended#4
Well i know X & Y is a Coldplay album......
#5
4(X+Y)(8-Y)(Xx4)

(4X+4Y)(32-4Y)(4Xx16)

(4X+4Y)(32-4Y)(64X)

(X+Y)(9-Y)(16X)


im LOST................???:oops:

if you are asking if I managed to get 26 out of all that then you are studying a level too high for you :p

I got 16x^2 + 4y^2 + 12xy + 32y

I dont think I have dealt with 3 brackets before tbh, and its been 11 years since i did gcse maths LOL!

-16yx^2 + 128x^2 - 16y^2x + 128yx


That's what i got too.
#9
n1ck09
-16yx^2 + 128x^2 - 16y^2x + 128yx


is this correct then or is MrsZ correct?
#10
Do you actually mean the third bracket to read (X x 4)????
Surely it would be written 4X??
Do you mean X+4??
Anyway, multiply it all up then simplify.
#11
i got this....
128X^2+128Y^2-16X^2Y-16Y^2X

or maybe this?

128X^2+128YX-16X^2Y-16XY^2

it's highly likely that the others are correct :-D

Refer to his/her last comment, if you think 26 is the answer then you need to get some extra help and take a step back to look at what algebra is. There is no equals in your equation. You also haven't posed a question, "what is the answer?" makes no sense, I assume you mean "expand out". Treat it as a number of smaller problems, first multiply out the last two sets of brackets, then multiply the result by the first set, then either leave the 4 out or combine, up to you.

agree...
you can't get a specif value for algebra equations.
the only value you can get is for the terms X and/or Y. however this equation has two unknowns therefore impossible to get a number value... :thinking:

This doesn't make sense to me either.

i havent got a clue about maths.. Im trying to help a friend by saying id ask the brainy peeps on HUKD.. thankyou all for your help :thumbsup:
#20
According to this you should multiply the 2nd and 3rd brackets together as you would usually, first - and then multiply this by the first bracket

What makes this one confusing is that you have (X x 4) rather than (X + 4) for example :thinking:

if it's for a friend, you may want to double check that they do mean (X [COLOR="Red"]x[/COLOR] 4) :thumbsup:

It isn't always easy to get things perfectly written on a blackberry, I have edited. However, I don't think it lost its meaning, whilst the original maths question posed could require numerous workings.

I agree. :thumbsup:
I, like you, still don't know what the question is. :?
