Question

find zero of the polynomial p(x)=2x+9

Answer 1

Here is your answer...>>>>>>>>


p(x)=2x+9

=p(0)=2x+9

=p(0)=2×0+9

=p(0)=0+9

=p(0)=9

Answer 2

1)if suppose value of x=0
then 
p(x)=2x+9
then replace x with the value 0
p(0)=2*0+9
p(0)=0+9
p(0)=9



2)Zero of the polynomial means, we have to find the value
of x such that after putting the value of x & solving it the answer we get should be 0.
So,
2x + 9 = 0
Now ,we take +9 on RHS hence , it will become -9
2x = -9
Now,
x =-9/2
Now we have got the value of x such that after putting the value & solving it we get the ans. as
