DIRECTION: Do as indicated. Give what is required in each activity.

Activity 1: Check your understanding by completing the table below.

Standard Form: ax² + bx + c =0


Example: x( 2x - 7) = 0

Standard Form: 2x² - 7x = 0

A: 2

B: -7

C: 0

1. (x + 5)( x + 9) = 20

2. (2x - 1)(x + 3) = -2x

3. (x + 6)² = 12x

4. (5x + 4) (5x - 4) = 0

5. (3x-8)(x+2) = 2x²​
