Answer 1

The first step in simplifying the difference \((2x^3−12x^2+5x−3)−(7x^3+10x^2−3x+20)\) is to distribute the negative to the second set of parentheses.

This involves changing the signs of all the terms in the second expression before combining like terms. So the correct response is:

Distribute the negative to the second set of parentheses.
