To expand the expression (5x² + 8x − 3)(6 − 4x), we can use the distributive property and multiply each term of the first expression by each term of the second expression:

(5x² + 8x − 3)(6 − 4x)

Expanding the expression:

= 5x² * 6 + 5x² * (-4x) + 8x * 6 + 8x * (-4x) - 3 * 6 - 3 * (-4x)

= 30x² - 20x³ + 48x - 32x² - 18 + 12x

Combining like terms:

= -20...
