Answer:
see explanation
Step-by-step explanation:
product means multiply
Given
(2x - 4)(5x² - 2x + 6)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(5x² - 2x + 6) - 4(5x² - 2x + 6) ← distribute both parenthesis
= 10x³ - 4x² + 12x - 20x² + 8x - 24 ← collect like terms
= 10x³ - 24x² + 20x - 24
