Multiplying polynomials — process?
Distribute each term and combine like terms.
Special products — examples?
Difference of squares and perfect square trinomials.
Difference of squares — formula?
(a + b)(a - b) = a² - b².
Perfect square trinomial — form?
(a + b)² = a² + 2ab + b².
Factoring out GCF — purpose?
Simplify polynomial by extracting common factors.
Factorization techniques — include?
Polynomial division, grouping, special products, trial and error.
Application example — polynomial expansion?
Expand (x + 2)(x + 3) to x² + 5x + 6.
Degree of product — relation?
Sum of degrees of factors.
Recognizing special products — benefit?
Speeds up multiplication and factoring.
Middle terms cancel — in which?
In conjugate binomials like (a + b)(a - b).
Perfect square trinomial — key feature?
Middle term is twice the product of the binomial terms.
Common mistake — during expansion?
Forgetting to combine like terms.
Difference of squares — quick factor?
Identify conjugates and apply (a + b)(a - b).
Application — simplifying (x + 4)²?
Expand to x² + 8x + 16.
