Answer:
The answer to your question is 10x⁵ - 29x⁴ + 33x³ - 18x² - 18x - 27
Step-by-step explanation:
Process
1.- Multiply
(2x - 3) (5x⁴ - 7x³ + 6x² - 9) = 10x⁵ - 14x⁴ + 12x³ - 18x - 15x⁴ + 21x³ - 18x² - 27
2.- Simplify like terms
= 10x⁵ + (-14x⁴ -15x⁴) + (12x³ + 21x³) + (-18x²) + (-18x)
- 27
= 10x⁵ - 29x⁴ + 33x³ - 18x² - 18x - 27
