Study Notes
Polynomial Division and Properties
- When dividing (x^2 - 1) by (x - 3), a placeholder of (-3x) is necessary for proper alignment.
- Dividing a polynomial by a monomial involves dividing each term of the polynomial individually by the monomial.
Factored Forms and Expansion
- The expression (x^3 - 9x^2 + 27x - 27) can be factored as ((x - 3)^3).
- Expansion of ((2y + 3)^2) results in (4y^2 + 12y + 9).
- The product ((4c + 5m)(4c - 5m)) simplifies to (16c^2 - 25m^2).
- The difference of squares formula is applied to ((w + 12)(w - 12)), resulting in (w^2 - 144).
Prime Expressions
- The expression (x^2 - 5) is considered prime, indicating it cannot be factored over the integers.
Polynomial Simplification
- The expression (y^2 - 2y - 4) can be rewritten as (\frac{y^3 - y^2 - 6y - 4}{y + 1}) showing the polynomial in terms of another variable.
