welcome students today I would be
0:02
presenting the polynomial concept for
0:04
class 9. so what is a polynomial the
0:08
word polynomial is made up of two terms
0:10
first one is poly which means many and
0:13
the second one is normies which means
0:15
terms so a polynomial has many terms it
0:18
can have any term having constants
0:20
variable and exponents but the exponent
0:24
should be a whole number now few
0:26
examples of polynomials are X Plus 1 5 5
0:29
minus X X Plus y plus Z and so on
0:34
now term under root X and 2 upon X plus
0:39
2 and exclude the power minus 2 are not
0:42
polynomials because an exponent is not a
0:45
whole number polynomials are also
0:47
classified based on numbers for example
0:50
polynomial with a single term or one
0:52
term is called monomial
0:55
and its example is simply X and the
0:58
polynomials with two terms are called
1:00
binomials for example X Plus 1 and a
1:03
polynomial with three terms are called
1:05
trinomial for example x square plus X
1:11
polynomial on one variable can be
1:14
generated by this equation where
1:16
polynomial s x is equals to A N X to the
1:19
power n plus a n minus 1 x to the power
1:22
n minus 1 plus a n minus 2 x to the
1:25
power n minus 2 and so on
1:28
here x is the variable
1:31
so in above equation a n a n minus 1 and
1:35
so on are called coefficient of x to the
1:37
power n x to the power n minus 1 n is
1:41
called degree of polynomial
1:43
if s x is equals to 0 it is called a
1:46
zero polynomial if s x is equals to A
1:50
naught it is called constant polynomial
1:52
and if for X is equals to A s x is
1:55
equals to 0 then a is called 0 of the
