Polynomial
The sum or difference of terms which
have variables raised to
positive integer powers and
which have coefficients that may be real or complex.
The following are all polynomials: 5x^{3} – 2x^{2} +
x – 13, x^{2}y^{3} +
xy, and (1 + i)a^{2} + ib^{2}.
Note: Even though the prefix poly means many,
we use the word polynomial to refer to polynomials with 1 term
(monomials),
2 terms (binomials), 3 terms, (trinomials), etc.
Standard form for a polynomial in one variable:
a_{n}x^{n} + a_{n}_{–1}x^{n}^{–1} + ··· + a_{2}x^{2} + a_{1}x + a_{0}
