Step-by-step explanation:
Generally from the table the contribution to the chi-square statistic of the number of individuals in the survey aged 20 - 22 who strongly disagreed about whether they observe packing information before purchasing items is mathematically represented as


We have been given a polynomial and we are asked to factor our polynomial by double grouping.

First of all we will group terms with common factors. We can see that
and 2x have a common factor x. Common factor of -3x and -6 is -3.


Now we will factor out Greatest Common Factor from each group.
After factoring out GCF from each group we got (x+2) as our common binomial. Now we will write our polynomial as a product of two binomials as:
Therefore, our polynomial as a product of two binomials will be
