Multiplying Polynomials

Find the product of the following polynomials:

(3x+2)(x-9)(2x+4)

• -136x+6x³-72+6x³

• 6x³-38x²-136x-72

• 6x³+38x²+136x+72

• -38x²-136x+6x³-72

Simplify:
(3x - 5) ( 4x² - 2x - 3)

• 12x³ - 26x² - 25x + 15

• 12x³ - 20x² - 5x + 15

• 12x³ - 20x² - 6x + 15

• 12x³ - 26x² + x + 15
