Answer :
Answer:
- 8
Step-by-step explanation:
Given
(3x² - 5)(4 + 4x²)
Each term in the second factor is multiplied by each term in the first factor, that is
3x²(4 + 4x²) - 5 (4 + 4x²) ← distribute both parenthesis
= 12x² + 12[tex]x^{4}[/tex] - 20 - 20x² ← collect like terms
= 12[tex]x^{4}[/tex] - 8x² - 20
The coefficient of the x² term is - 8
