Is the difference of two polynomials always a polynomial? Explain.
take this \(x^2 +x+2\) and \(x^2 +x+4\) are their difference a polynomial?
the two expressions are polynomials rite?
but subtracting the second from the first, gives us an integer, which is not a polynomial. This is a counter example
so the answer is
It is shown that it's no.
Hmm ... I believe that integers are polynomials. An integer is simply a polynomial of degree zero.
well, it seems so...though that would means any expression is a polynomial as long as the degree is a positive integer
f(x)=0 f(x)=-3 are both polynomials to get the definition of polynomial: http://en.wikipedia.org/wiki/Polynomial
degree is non-negative, so it can be 0 degree
