Final answer:
To multiply the given expressions, use the distributive property to multiply each term in one expression by each term in the other expression and then combine like terms.
Step-by-step explanation:
To multiply the given expressions (3x²-2x-1) and (2x²+x-5), we can use the distributive property. First, we multiply each term in the first expression by each term in the second expression and then combine like terms.
Using this approach, we get:
(3x²-2x-1) × (2x²+x-5) = 6x4 + 3x³ - 15x² - 4x³ - 2x² + 10x + 2x² + x - 5 = 6x4 - x³ - 17x² + 11x - 5
