Why
is ‘x’ the unknown?

(Summary)
Terry
Moore on TED.com :
The common question
about “ why is it that the letter X represents the unknown?” has already found
by Mr. Moore.
About six years ago Mr.
Moore decided to learn Arabic, which recognize as supremely logical language.
He also argued that, In writing a word or phrase or sentence is like crafting
an equation, because every part carries a lot of information. One of the reasons that so much to think of
as Western science, mathematics and engineering that really affected of the
common Era by the Persians, Arabs, and Turks.
This includes the
little system in Arabic called al-jebra.When
the Arabian arrived in their way to Europe in 11th and 12th centuries, they
were interested in translating the wisdom into a European language. But, the
problems are some Arabic sounds unfamiliar with European unless they have lots
of practice and the sounds tend not to be represented by European language
character. Arabic has a letter Sheen ‘sh’; first letter of word Shai un
“something” and ‘al’ as definite which
means al-shai un “the unknown thing”. In contrary, Spanish language doesn’t
have SH sound, so by convention, they created a rule in which they borrowed the
CK sound ‘ck’ from the classical Greek in the form of the letter Kai.
Later, when this
material was translated into a common European language, which is to say Latin,
they simply replaced the Greek Kai with the Latin X. Hence, the answer of X is
unknown because Spanish cannot say ‘sh’
