Notes
- Adding and Subtracting Polynomials
- Just collect like terms!
- Multiplying Polynomials
- When multiplying 2 polynomials, multiply every term in the first polynomial by every term in the second polynomial.
- You can line up terms with the same power and multiply like you did before your grapher.
- When you need to multiply three polynomials, just multiply any two of them, and then multiply their product by the third polynomial, being sure to follow orders of operations. You can do the same thing with four or more polynomials, too.
