HOW TO SOLVE (a-m)(b-m)..(x-m)(y-m)(z-m)

OpenStudy (anonymous):

is anyone there\

OpenStudy (dangerousjesse):

Distribute.

OpenStudy (anonymous):

how

OpenStudy (dangerousjesse):

(abcdefghijklmnopqrstuvwxyz)\(\times\)(26m)=?

OpenStudy (anonymous):

0

OpenStudy (anonymous):

?

OpenStudy (dangerousjesse):

I meant (abcdefghijklmnopqrstuvwxyz)-(26m)=?

OpenStudy (dangerousjesse):

No. Not zero.

OpenStudy (anonymous):

doesnt it stay the same?

OpenStudy (dangerousjesse):

You're not saying (26m)-(26m). Just (abcdefghijklmnopqrstuvwxyz)-(26m)=?. Yes, it stays the same.

OpenStudy (anonymous):

no it doesnt\

OpenStudy (dangerousjesse):

I'm fairly sure it does. There is nothing for you to go on but the alphabet.

OpenStudy (anonymous):

what about m-m

OpenStudy (dangerousjesse):

It's not m+n+o, it's m\(\times\)n\(\times\)o. You can't take away from the product.

OpenStudy (anonymous):

hmmm

OpenStudy (dangerousjesse):

Oh! I see where you're coming from. Gah, I'm so dense. That would leave you with 0 \(\times\) any random number, and commutative property wouldn't apply to that, so you have to leave it be.

OpenStudy (anonymous):

so the answer is 0?

OpenStudy (anonymous):

lol im still very confused

OpenStudy (zarkon):

it is zero...because of the m-m term

OpenStudy (anonymous):

elaborate i still dont understand...

OpenStudy (zarkon):

(a-m)(b-m)...(l-m)(m-m)(n-m)...(y-m)(z-m) =(a-m)(b-m)...(l-m)(0)(n-m)...(y-m)(z-m)=0

OpenStudy (anonymous):

(a-m)(b-m) so -m-m

OpenStudy (anonymous):

(a-m)(b-m)=ab-m^2????????????????????????????????????/

OpenStudy (zarkon):

if you want (a-m)(b-m) you get \[ab-am-mb+m^2\]

OpenStudy (anonymous):

GAAAAAAAAAAAAAAAHHHHHH...loll

OpenStudy (anonymous):

that would give you m^2 no?

OpenStudy (zarkon):

?

OpenStudy (anonymous):

ok when you look at the operation do you see -m-m ?

OpenStudy (zarkon):

no

OpenStudy (zarkon):

i see an .... m-m

OpenStudy (zarkon):

which is zero

OpenStudy (anonymous):

but before the st m is a -

OpenStudy (anonymous):

1st*

OpenStudy (zarkon):

this is just a bunch of multiplication...one of the terms is (m-m)=0. Therefore the entire product is zero
