Factoring polynomials in one variable of degree $2$ or higher can sometimes be done by recognizing a root of the polynomial. In the case of a polynomial with more than one variable, the degree is found by looking at each monomial within the polynomial, adding together all the exponents within a monomial, and choosing the largest sum of exponents. Polynomial regression looks quite similar to the multiple regression but instead of having multiple variables like x1,x2,x3… we have a single variable x1 raised to different powers. For example, x + y and x 2 + 5y + 6 are still polynomials although they have two different variables x and y. Review of Taylor polynomials in one variable. Polynomial in one variable “An expression which consists of only one type of variable in the entire expression is called polynomial in one variable”. This is called the derivative with respect to x and is denoted by dP/dx. By the same token, a monomial can have more than one variable. For example, 2 × x × y × z is a monomial. The coefficient of the leading term is called the leading coefficient. Give reasons for your answer. When a polynomial has more than one variable, we need to look at each term.
