The expression that represents the difference of the polynomials is: 2x - 7y.
Given the two polynomials, (-4x – 3y) and (–2x – 10y), to subtract them, open the bracket and combine like terms.
(–2x – 10y) - (-4x – 3y)
–2x – 10y + 4x + 3y
Combine like terms
-2x + 4x - 10y + 3y
2x - 7y
Thus, the expression is: 2x - 7y
