Question

Which of the following is a polynomial

A. 1-5x^2/x
b. 11x
c. 2x^2- square root x
d. 3x^2+6x

Answer 1

B and D are polynomial

Explanation:

An algebraic expression with non-zero coefficients and variables having non-negative integers as exponents is called a polynomial.

A)

If it is
`1 -(5x^(2))/(x )=1-5x` , then it is a polynomial.

But if it is
`(1-5x^(2))/(x)` then it is not a polynomial
