Question

Verify whether the values of x = -1/3 and x = 1/2 are the zeros of the polynomial P(x) = 3x+1 or not​

Answer 1

Answer:

x = -1/3

P(x) = 3x+1

• = 3×(-1/3) +1
• = -1+1
• = 0

-1/3 is the zero of the polynomial

x = 1/2

P(x) = 3x+1

• =3×1/2+1
• =3/2+1
• = 5/2

x = 1/2 is not the zero of the equation

Answer 2

Answer:

if x= -1/3

p(-1/3)=3(-1/3)+1

=-1+1

=0

if x=1/2

p(1/2)= 3(1/2)+1

=3/2+1

=5 /2

only -1/3 is the zero of the given polynomial
