Question

answer it fast and easy​

Answer 1

1) It is not a polynomial

As [(x-2)(x-4)]/x = [(x-2)(x-4)] * 1/x

1/x = x^(-1)

It is negative power. So it is not a polynomial

2) It is not a polynomial

1/{(5x)^-2 + 5x^7/7

= 5x^2 +5x^7*(1/7)

1/7 = 7^(-1)

It is negative power. So it is not a polynomial.
