Question

Which of the following is a polynomial with only one zero ? 

A) p(x) = 2x² – 3x + 4 

B) p(x) = x² – 2x + 1 

C) p(x) = 2x + 3 

D) p(x) = 5

Answer 1

Correct option is (C) p(x) = 2x + 3

If a polynomial equation has n degree then number of zeros of that polynomial equation is n.

In among all options p(x) = 2x+3 is a linear polynomial which is a polynomial of degree 1.

Thus, it has only 1 zero.

Answer 2

Correct option is C) p(x) = 2x + 3
