Algebra: Polynomials, rational expressions and equations

Expressions that are products of numbers, variables, and their degrees are called monomials. Expressions that are sums or differences of two or more monomials are called polynomials. A polynomial where there are no similar monomials, is called the polynomial in standard form. A degree of a monomial is the sum of powers of its variables. Degree of is 2+3=5. A degree of a polynomial is the maximum degree of its monomials. Degree of is 4. When submitting questions to tutors, use the caret symbol ^ to denote powers. x^2 means x squared.
