The polynomial 10x3 + 35x2 − 4x − 14 is factored by grouping. 10x3 + 35x2 − 4x − 14 − what is the common factor that is missing from both sets of parentheses? −2x − 7 2x + 7 −2x2 + 7 2x2 + 7

Option B 2x+7 is correct.

Step-by-step explanation:

We need to solve the polynomial by factored by grouping.

10x^3 + 35x^2-4x-14

Taking 5x^2 common from 1st 2 terms and -2 common from last 2 terms, the term inside the bracket will be 2x+7

5x^2(2x+7)-2(2x+7)

So, Option B 2x+7 is correct.

Option B is right

Step-by-step explanation:

Given:

Given is a cubic polynomial as

To factorise:

the given polynomial.

The terms are grouped into pairs as follows:

We factorise each pair as follows

=

Thus we find that the missing term is

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
