## Lesson 2: Solving Quadratic Equations ### Factoring Polynomials **Recall:** Factoring polynomials - Factoring by GCF or common monomial/ factor. - Factoring perfect square trinomials. - Factoring general trinomial of the form x² + bx + c. - Factoring general trinomial in the form ax² + bx + c. ### Factoring Difference of the Squares The factor of differences of two squares is the product of sum and difference of these terms **Example** - x² -100 = (x+10)(x-10) - 9y² - 81 = (3y + 9)(3y - 9) - 81m² - 4 = (9m + 2)(9m - 2) **Factoring:** - 9y² - 25 = (3y + 5)(3y - 5) - 49k² - (ab²c³ + 7k²) = 49k² - (ab²c³ + 7k²)
