Given:

The trinomial equation is given as,

[tex]3v^2-4v-7[/tex]

The objective is to choose the correct value for which the factors are to be obtained for factorization.

Explanation:

From the step 1, to perform the factorization the values of a and c has to be multiplied.

Then in step 2, the factors need to be calculated for the product of a and c.

Product of a and c :

The product of a and c will be,

[tex]a\times c=3\times7=21[/tex]

Thus, factors are to be listed for the number 21.

Hence, option (1) is the correct answer.
