Find the corresponding values on the box provided below. Application Directions: Solve the following quadratic equation by factoring. Steps to solve Quadratic Equation by Factoring 4. Abstraction ➔ Ask the student to define the following a. x = 0 or x = - Step 4: Check the values of the variable obtain by substituting each in the original equation. 6x = 0 or x + 3 = 0 Step 3: Solve each of the resulting equations. 6x 2 + 18x = 0 6x(x + 3) = 0 Step 2: Set each factor equal to zero. Find the roots of the equation 6x 2 + 18x = 0 Solution: Step 1: Obtain zero on one side and then factor. x = 3 or x = - Step 4: Check the values of the variable obtain by substituting each in the original equation. x – 3 = 0 or x + 5 = 0 Step 3: Solve each of the resulting equations. x 2 + 2x – 15 = 0 (x – 3) (x + 5) = 0 Step 2: Set each factor equal to zero. Find the solutions of x 2 + 2x – 15 = 0 Solution: Step 1: Obtain zero on one side and then factor. ➔ Show example JUMBLED LETTERS ANSWER CTORGINAF FACTORING VILOSGN SOLVING CQURTIADA QUADRATIC SAMACITTHEM MATHEMATICS TIQUAOSNE EQUATION ▪ Example 1.
