## Study Notes

### Polynomials

#### Addition and Subtraction of Polynomials

- To add or subtract polynomials, combine like terms:
- Combine terms with the same variable(s) and exponent(s)
- Add or subtract coefficients
- Simplify the result

- Example:
`(3x^2 + 2x - 1) + (2x^2 - 4x - 3) = ?`

- Combine like terms:
`5x^2 - 2x - 4`

- Combine like terms:
- Important to note:
- You can only add or subtract polynomials with the same variables and exponents

#### Factoring Polynomials

- Factoring is the process of expressing a polynomial as a product of simpler expressions
- Types of factoring:
- Greatest Common Factor (GCF):
`ax + ay = a(x + y)`

- Difference of Squares:
`a^2 - b^2 = (a + b)(a - b)`

- Sum and Difference:
`a^2 + 2ab + b^2 = (a + b)^2`

and`a^2 - 2ab + b^2 = (a - b)^2`

- Greatest Common Factor (GCF):
- Example: Factor
`x^2 + 5x + 6`

- Look for two numbers whose product is 6 and sum is 5:
`2`

and`3`

- Factor:
`(x + 2)(x + 3)`

- Look for two numbers whose product is 6 and sum is 5:

#### Multiplication of Polynomials

- To multiply polynomials, use the distributive property:
- Multiply each term in one polynomial by each term in the other polynomial
- Combine like terms
- Simplify the result

- Example:
`(2x + 3)(x + 4) = ?`

- Multiply each term:
`2x^2 + 8x + 3x + 12`

- Combine like terms:
`2x^2 + 11x + 12`

- Multiply each term:
- Important to note:
- Be careful when multiplying polynomials with multiple terms and variables
