Answer:
108 - 30x - 116x² - 18x³
Step-by-step explanation:
We have to get the value of - (2x + 12) (9x² + 4x - 9)
Now, using the distributive property of multiplication we get
- (2x + 12) (9x² + 4x - 9)
= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]
= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]
= -[18x³ + 116x² + 30x - 108]
= 108 - 30x - 116x² - 18x³ (Answer)
