Heres the formula and steps
Answer:
18x⁴ - 30x³ + 66x² - 40x + 56
Step-by-step explanation:
1) Distribute
- (6x² + 8) (3x² - 5x + 7)
- 6(3x² - 5x + 7) x² + 8(3x² - 5x + 7)
2) Distribute
- 6(3x² - 5x + 7) x² + 8(3x² - 5x + 7)
- 18x⁴ - 30x³ + 42x² + 8(3x² - 5x + 7)
3) Distribute
- 18x⁴ - 30x³ + 42x² + 8(3x² - 5x + 7)
- 18x⁴ - 30x³ + 42x² + 24x² - 40x + 56
4) Combine like terms
- 18x⁴ - 30x³ + 42x² + 24x² - 40x + 56
- 18x⁴ - 30x³ + 66x² - 40x + 56
