Multiply the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of a. (4x^2 - 10x - 24) (2x + 3)

2 (2x + 3) ² (x - 4)

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

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

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

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

2 (2x + 3) (2x² + 3x - 8x + 12)

2 (2x + 3) (2x² - 5x - 12)

(2x + 3) (2 (2x² - 5x - 12))

(2x + 3) (2 (2x²) - 2 (5x) - 2 (12))

(2x + 3) (4x² - 10x - 24)

2x (4x² - 10x - 24) + 3 (4x² - 10x - 24)

2x (4x²) - 2x (10x) - 2x (24) + 3 (4x²) - 3 (10x) - 3 (24)

8x³ - 20x² - 48x + 12x² - 30x - 72

8x³ - 20x² + 12x² - 48x - 30x - 72

8x³ - 8x² - 78x - 72
