Answer:

(x -1)(12x +13)

Step-by-step explanation:

You are looking to rewrite the middle term as the sum of terms that have factors of (12)(-13) that have a total of +1. Those factors are -12 and +13, so the expression you are factoring by grouping is ...

12x^2 +13x -12x -13

= x(12x +13) -1(12x +13)

= (x -1)(12x +13)
