Factorise (m+1)^2 - 9
February 12th 2011, 03:20 AM
Factorise (m+1)^2 - 9
(m+1)Square -9
My answer : (m-8)(m+8)
And also, is it true that we can't write capital letters for algebra? only small letters.
Thanks so much for helping!
February 12th 2011, 03:31 AM
Unfortunately, no, that's not the answer.

up vote 3 down vote favorite

Let $d$ be a metric. Then $-d(x,y)/b+1... | {"url":"http://mathoverflow.net/questions/11294/do-all-correlation-coefficients-induce-a-pseudometric","timestamp":"2014-04-19T20:24:56Z","content_type":null,"content_length":"51002","record_id":"<urn:uuid:cad132ca-f6a7-47ac-b023-1e0739bb1d74>","cc-path":"CC-MAIN-2014-15/segments/1397609537376.43/warc/CC-MAIN-201404160... |
