To expand the expression (−3x − 5)(−2x² − 3x − 4) 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 − 5)(−2x² − 3x − 4)

Expanding the expression:

= (-3x)(-2x²) + (-3x)(-3x) + (-3x)(-4) + ...
