Study Notes

Multiplying Polynomials Part 1

This lesson is an extension of previous lessons on multiplying terms and binomials.
Multiplying any kind of polynomials together becomes mechanical once the concepts are understood.
Distributing terms is the key to multiplying polynomials.
The FOIL method is simply a way to distribute terms when multiplying binomials.
To multiply a binomial and a trinomial, each term in the trinomial must be multiplied by each term in the binomial.
The number of terms in the product of two polynomials is equal to the product of the number of terms in each polynomial.
Negatives and positives must be carefully multiplied to get the right signs in the final answer.
It is important to master the skill of multiplying polynomials as it is used in many other topics in algebra.
The process of multiplying polynomials is the same regardless of the number of terms in each polynomial.
Fingers can be used to keep track of terms when distributing.
Simplifying like terms is necessary in the final answer.
The key to success is understanding the concepts and practicing the mechanical process.Multiplying Polynomials: Binomials and Trinomials
To multiply binomials, distribute each term of the first binomial to each term of the second binomial.
To multiply trinomials, distribute each term of the first trinomial to each term of the second trinomial.
When multiplying, add the exponents of like terms with the same base.
To check your answer, simplify and combine like terms.
To multiply polynomials with higher exponents, follow the same pattern of distribution.
The number of terms in the answer will be the product of the number of terms in each polynomial being multiplied.
When combining like terms, terms with the same exponent degree can cancel each other out.
The final answer should be simplified and written in descending order of exponents.
The same rules apply when multiplying any number of polynomials.
As the number of terms in the polynomials being multiplied increases, the number of terms in the answer also increases.
Understanding how to multiply polynomials is foundational for more complex algebraic equations.
