Hope it helps you.

Answer 2

Answer:

1) 4x^3/2+/x^1/2 is not a polynomial

Step-by-step explanation:

(a) x

2

×

x

=x

2

+x

−1

is not a polynomial since the exponent of variable in 2nd term is negative.

(b) 2x

−3

x

+1=2x

2

−3x

1

+1 is not a polynomial, since the exponent of variable in 2nd terms is a rational number.

(c) x

3

−3x+1 is a polynomial.

(d) 2x
