So how can we solve

6x²-13x-5=0

We could use "complete the square" I've attached an image of what that is like. Either you will find it "satisfying and elegant" or the fractions will make it feel like not much fun. The quadratic formula is much the same.

So, back to FACTORING we want two binomials that multiply to:

6x²-13x-5=0

So we need the first terms in each to multiply to 6x² the last terms in each to multiply to -5. And the factors of 6*(-5) =-30 to add to the middle term.
