let us move on to the third part is an
entity expression with coefficient so
what is the coefficient to the numerical
factors are called as coefficient so
just now I spoke about a both algebraic
and numeric factors let us look at it in
more detail let's talk about the same
example 13 minus y plus 5 y square so in
this what are the terms so let us first
write down the terms one term is 13 the
second term is minus y and the third
term is 5 y square so these are the
three terms now what are the factors so
if you look at a factor you see the
first term 13 do you think 13 can be
factorized further no 13 cannot be
factorized for this what about -1 do you
think - Y can be baptized for this
where - Y can be factorized further it
can be written as minus 1 into y
similarly file
gooble square can be factorized further
it can be written as 5 into y into y
right so here we see that minus 1 what
is this minus 1 this minus 1 is a
numerical factor of Y because it is a
factor of Y and it is also a numeric
similarly when you look at this file so
this 5 is also a numeric factor of Y so
here in this case we can say that minus
1 and 5 are the coefficient for this
expression so likewise if you have an
expression or if you have a term like
the 7 extra square so in this term what
would be the coefficient of a
coefficient is always a numerical factor
so coefficient of x would be 7 if you
have an expression like minus 3 y cube
so what would be the coefficient of well
in this case the coefficient would be
minus 3 if you have junk
like why so what would be the
coefficient of right the coefficient in
this case would be one how about the
coefficient of minus y so my position of
Y in this case would be minus one so
these are various examples where I
showed you how do we find out efficient
in an algebraic expression and
coefficient values with respect to a
variable so sometimes you might come
across an to be expressions where you
have multiple variables you have eight
you want one five you're grounded so in
that case if you are asked to find out
for patients with your proficient will
always be with respect to a particular
variable like coefficient of x in this
vegetation or coefficient of Y in this
expression so you will calculate the
position in that fashion so okay with
this I think we got an idea about the
different parts of an algebraic
expression and expression has stones and
information has factors and for the
numerical factor specially raised to
special term well coefficient thank you
