What is the product (2x - 9)(3x + 5)?​

Answers

Answer 1
Answer:

Answer:

6x² - 17x - 45

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor

(2x - 9)(3x + 5)

= 2x(3x + 5) - 9(3x + 5) ← distribute both parenthesis

= 6x² + 10x - 27x - 45 ← collect like terms

= 6x² - 17x - 45
