Factoring Special Products
Learning Objective
I can factor special products like difference of squares and perfect square trinomials.
Key Concepts
When factoring special case polynomials, remember that a² - b² can be factored into (a + b)(a - b).
A perfect square trinomial in the form a² + 2ab + b² can be factored into (a + b)² and a² - 2ab + b² factors into (a - b)².
To factor a polynomial like 16n² - 9, recognize a = 4n and b = 3, so the factored form is (4n + 3)(4n - 3).
