If x2+4x3/2 a polynomial .justify your answer

Question

It is from the chapter polynomial

Answer 1

If this is meant to be x^2+4x^(3/2) then it isn't a polynomial, because we have a non-integer power of the variable. Polynomials have integer powers by definition, and the integers must be positive.

If it's meant to be x^2+(4x^3)/2 then it is a polynomial, but then you would have to ask why it isn't shown as x^2+2x^3.

Answer 2

x^2X+4X^(3/2
x^2+(4x^3)/2
x^2+2x+^3
