Question
Define a polynomial with real coefficients.
Solution
In the polynomial `f(x)=a_nx^n+a_(n-1)+......+a_1x+a_o`,
`a_nx^n,a_(n-1x^(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
