# Polynomial expressions

A polynomial with two indeterminates is called a bivariate polynomial. In the case of polynomials in more than one indeterminate, a polynomial is called homogeneous of degree n if all its non-zero terms have degree n.

A polynomial of degree zero is a constant polynomial or simply a constant. Note that in this definition Polynomial expressions is implied that the value of the expression is not changed - only its form.

However, we can still make a guess as to the initial form of the factoring. Since this type of multiplication is so common, it is helpful to be able to find the answer without going through so many steps. Notice that in each of the following we will have the correct first and last term.

You may select which type of polynomials problem to use and the range of numbers to use as the constants. In this case the correct factorization is: First look for common factors.

Solution Here both terms are perfect squares and they are separated by a negative sign. However, they will increase speed and accuracy for those who master them.

A prime expression cannot be factored. The term "quadrinomial" is occasionally used for a four-term polynomial.

Since the first and last positions are correctly filled, it is now only necessary to fill the other two positions. You must also be careful to recognize perfect squares. Polynomials of degree one, two or three are respectively linear polynomials, quadratic polynomials and cubic polynomials.

Select the expression that is equivalent Select all expressions that are equivalent: They may not use a calculator on the exam until they have delivered the non-calculator page to my desk. The factors of 15 are 1, 3, 5, I give students both pages of the test at the beginning of the period and instruct them not to put their calculators under their chairs.

Solution The last term is negative, so unlike signs. Again, find the greatest common factor of the numbers and each letter separately. To check the factoring keep in mind that factoring changes the form but not the value of an expression.

This allows them to budget their time, as they can see the entire test at once. Random Factoring The process of factoring is essential to the simplification of many algebraic expressions and is a useful tool in solving higher degree equations. Sometimes when there are four or more terms, we must insert an intermediate step or two in order to factor. When the coefficient of the first term is not 1, the problem of factoring is much more complicated because the number of possibilities is greatly increased. To factor an expression by removing common factors proceed as in example 1.

This monomial and polynomial worksheet will produce six problems per page. Because the degree of a non-zero polynomial is the largest degree of any one term, this polynomial has degree two. Thus trial and error can be very time-consuming. You may select the number of problems, the types of expressions, as well as the parities of both the powers and constants. To factor the difference of two squares use the rule To factor a perfect square trinomial form a binomial with the square root of the first term, the square root of the last term, and the sign of the middle term and indicate the square of this binomial.

Multiplying Special Case Polynomial Worksheets This monomial and polynomial worksheet will produce problems for multiplying special case polynomials. The original expression is now changed to factored form. It is possible to further classify multivariate polynomials as bivariate, trivariate, and so on, according to the maximum number of indeterminates allowed.

Factoring Polynomials. Factoring a polynomial is the opposite process of multiplying polynomials. Recall that when we factor a number, we are looking for prime factors that multiply together to give the number; for example.

6 = 2 × 3, or 12 = 2 × 2 × 3. When factoring trinomial expressions (or other polynomial expressions), it is useful to look for a GCF as your first step. Don’t forget to look for these special cases.

Examples of How to Add and Subtract Polynomials. Example 1: Simplify by adding the polynomial expressions. The key in both adding and subtracting polynomials is to make sure that each polynomial is arranged in standard form. The polynomial expression in one variable, becomes the matrix expression where X is a square matrix and I is the identity matrix.
