Explanation:

Answer 2

Choice A

Explanation:

I would recommend starting off by using the distributive property.

(7x + 5)(2x³ - 4x² + 9x - 3) = 7x(2x³ - 4x² + 9x - 3) + 5(2x³ - 4x² + 9x - 3)

then simplify

= (14x^4 - 28x³ + 63x² - 21x) + (10x³ - 20x² + 45x - 15)

Now add it all together

= 14x^4 - 18x³ + 43x² + 24x - 15

The answer is choice A
