//Kelly Truong, Period 1// //**Factoring Expressions:**// Problem #1: 6x^2-15y 1,6 1,5 2,**3** **3**,5 x y x
 * Answer:** 3(2x^2 + y + 5)

__//**Zero-Product Property:**//__ __Problem #2: (c + 6)(c + 8) =0__ __c+6=0 c+8=0__ Solve This Problem: __a^2+5a=0__
 * Answer:** c= -6 c= -8

//Chapter 9.4// **//Solve Polynomial Equations in Factored Form//**

//Solving polynomials will help to analyze vertical motion.//

**Problem 1** : (x - 5) (x + 3) = 0 **Solution** : (x - 5) (x + 3) = 0 x - 5 = 0 | x + 3 = 0 + 5 + 5 | - 3 - 3 x = 5 | x = -3

**Problem 2** : 2x + 2y **Solution** : 2x + 2y 1, **2**, x | 1, **2**, y 2 (x + y)
