Answer:
- 9x² - 36x - 27
Step-by-step explanation:
9 - (3x + 6)² ← expand using FOIL
= 9 - (9x² + 36x + 36) ← distribute parenthesis by - 1
= 9 - 9x² - 36x - 36
= - 9x² - 36x - 27
All Real Numbers
Step 1:
3x - 9 = 3 ( x - 3 ) Equation
Step 2:
3x - 9 = 3x - 9 Multiply
Step 3:
- 9 = - 9 Subtract 3x on both sides
