Find the zero of the polynomial:

(i) P(x)=x-5


(ii) q(x)=x+4


(iii) p(t)=2t-3


(iv) f(x)=3x+1


(v) g(x)=5-4x


(vi) h(x)=6x-1


(vii) p(x)=ax + b,a≠0


(viii) q(x) = 4x


(ix) p(x)=ax,a≠0


(i) At first,


In order to find the zero of the polynomial we will,


Put p(x) = 0


Now,


We have,


P(x)=x-5


0 = x – 5


x = 5


Hence, 5 is the zero of the given polynomial.


(ii) At first,


In order to find the zero of the polynomial we will,


Put q(x) = 0


Now,


We have,


q(x)=x+4


0 = x + 4


x = - 4


Hence, -4 is the zero of the given polynomial.


(iii) At first,


In order to find the zero of the polynomial we will,


Put p(t) = 0


Now,


We have,


P(t)= 2t - 3


0 = 2t – 3


2t = 3


t = 3/2


Hence, 3/2 is the zero of the given polynomial.


(iv) At first,


In order to find the zero of the polynomial we will,


Put f(x) = 0


Now,


We have,


f(x)= 3x + 1


0 = 3x + 1


3x = -1


x =


Hence, -1/3 is the zero of the given polynomial.


(v) At first,


In order to find the zero of the polynomial we will,


Put g(x) = 0


Now,


We have,


g(x)= 5 – 4x


0 = 5 – 4x


4x = 5


x = 5/4


Hence, 5/4 is the zero of the given polynomial.


(vi) At first,


In order to find the zero of the polynomial we will,


Put h(x) = 6x - 1


Now,


We have,


h(x)= 6x- 1


0 = 6x – 1


6x = 1


x = 1/6


Hence, 1/6 is the zero of the given polynomial.


(vii) At first,


In order to find the zero of the polynomial we will,


Put p(x) = 0


Now,


We have,


p(x)= ax + b


0 = ax + b


ax = -b


x = (-b)/a


Hence, (-b)/a is the zero of the given polynomial.


(viii) At first,


In order to find the zero of the polynomial we will,


Put q(x) = 0


Now,


We have,


q(x)= 4x


0 = 4x


x = 0


Hence, 0 is the zero of the given polynomial.


(ix) At first,


In order to find the zero of the polynomial we will,


Put p(x) = 0


Now,


We have,


p(x)= ax


0 = ax


x = 0


Hence, 0 is the zero of the given polynomial.
