Question

Which of the following are polynomials?
(A) 1/√x + 13 + 5x
(B) 3x³ +4x² +√2x - 4/3
(C) (√x - 1/√x)²

Answer 1

Answer:

B)3x^3 + 4x^2 + x^1/2 -4/3

Step-by-step explanation:

the presence of x^1/2 or of this stuff makes an expression non-polynomial ...

the basic definition of polynomials is that the exponent of x should be non-negative integer ...

so x cannot come in denominator or x cannot have negative power or rational exponent
