Answer:

The common factors should be used in the next step of factoring is x² and -2.

Explanation:

Consider the provided expression.


10x^3+3x^2-20x-6

Factor the above expression by grouping.


(10x^3 + 3x^2) + (-20x -6)

Factor out x² form the first parentheses and -2 from the second parentheses.


x^2(10x+3) -2 (10x+3)

Hence, the common factors should be used in the next step of factoring is x² and -2.
