Question

Define a polynomial with real coefficients.

Answer 1

In the polynomial `f(x)=a_nx^n+a_(n-1)x^(n-1)+...+a_1x+a_0`, 

`a_nx^n,a_(n-1)x^(n-1),...,a_1x`, and `a_0` are known as the terms of the polynomial and `a_n,a_(n-1),...,a_1` and `a_0` are their real coefficients.

For example, `p(x)=3x-2` is a polynomial and 3 is a real coefficient.
