Question

Teresa is factoring this polynomial by grouping. Which common factors should be used in the next step of factoring? 10x3+3x2−20x−6 (10x3+3x2)+(−20x−6)

Answer 1

Answer:C

Step-by-step explanation:

Answer 2

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.

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

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.
