To expand the expression (−5x − 3)(−3x² − 2x − 1) 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.

(−5x − 3)(−3x² − 2x − 1)

Expanding the expression:

= (-5x)(-3x²) + (-5x)(-2x) + (-5x)(-1) ...
