Factoring the trinomial:
we get the factors 
Step-by-step explanation:
We need to factor the trinomial: 
We can factor the trinomial by breaking the middle term i.e 13x
Such that adding or subtracting gets the both terms we get 13x and multiplying both terms we get 12x^2
We can break 13x as: 12x and x
Adding them we get 13x and multiplying them we get 12x^2
So,

So, Factoring the trinomial:
we get the factors
