To expand the expression (−3x − 4)(−4x² − 5x − 6) into a polynomial in standard form, we need to multiply each term of the first expression by each term of the second expression and then combine like terms.

(−3x − 4)(−4x² − 5x − 6)

Expanding the expression:

= (-3x)(-4x²) + (-3x)(-5x) + (-3x)(-6) + (-4...
