Question

is the expression 4x^3-3.6x^2-sqrt2 a polynomial

Answer 1

Well, with respect to \(x\) is is a polynomial because it only has natural number exponents.

Answer 2

@domingo is that a whole root your saying is towards the end?

Answer 3

If its a whole root, then the answer is no. Cause a polynomial should have whole no.s as powers and not fractions :-)

Answer 4

P(x) = 4x^3 - 3.6x^2 - sqrt2 has real numbers as coefficients and the powers of x are whole numbers. So, yes, it is a polynomial.
