( 3X^2 - 5)( 4x^3 +7x + 2).
1 answer:
Answer:
12 + x³ + 6x² - 35x - 10
Step-by-step explanation:
(3x² - 5)(4x³ + 7x + 2)
Each term in the second factor is multiplied by each term in the first factor, that is
3x²(4x³ + 7x + 2) - 5(4x³ + 7x + 2) ← distribute parenthesis
= 12 + 21x³ + 6x² - 20x³ - 35x - 10 ← collect like terms
= 12 + x³ + 6x² - 35x - 10
