Basic Polynomial Operations
Adding polynomials
To add polynomials, simply combine like terms. Like terms are terms that have the same variables and exponents. For example, the terms 2x^2 and 3x^2 are like terms, but the terms 2x^2 and 3x are not.
Subtracting polynomials
To subtract polynomials, simply change the signs of all the terms in the second polynomial and then add the two polynomials.
Multiplying polynomials
To multiply polynomials, you can use the distributive property and the product of sums rule.
Dividing polynomials
There are two main ways to divide polynomials: long division and synthetic division.
Advanced Polynomial Operations
Factoring polynomials
Factoring polynomials is the process of breaking down a polynomial into smaller, more manageable polynomials. There are a variety of factoring methods, such as factoring by grouping, factoring by common factors, and factoring by the quadratic formula.
Finding the greatest common factor (GCD) of polynomials
The greatest common factor (GCD) of two or more polynomials is the largest polynomial that is a factor of all of the polynomials. The GCD can be found using the Euclidean algorithm.
Finding the least common multiple (LCM) of polynomials
The least common multiple (LCM) of two or more polynomials is the smallest polynomial that is a multiple of all of the polynomials. The LCM can be found using the following steps:
- Find the GCD of the polynomials.
- Divide each polynomial by the GCD.
- Multiply the resulting polynomials together.
Solving polynomial equations
There are a variety of ways to solve polynomial equations, such as factoring, using the quadratic formula, and using graphing.
Finding the derivative and integral of polynomials
The derivative of a polynomial is the expression that represents the rate of change of the polynomial. The integral of a polynomial is the expression that represents the area under the curve of the polynomial function.
