Answer:
The common factors should be used in the next step of factoring is x² and -2.
Step-by-step explanation:
Consider the provided expression.
[tex]10x^3+3x^2-20x-6[/tex]
Factor the above expression by grouping.
[tex](10x^3 + 3x^2) + (-20x -6)[/tex]
Factor out x² form the first parentheses and -2 from the second parentheses.
[tex]x^2(10x+3) -2 (10x+3)[/tex]
Hence, the common factors should be used in the next step of factoring is x² and -2.
