Do you mean factoring it?

First factor out the common 4:


Now turn your attention to the trinomial:


This is called the "ac" method.

Multiply the leading coefficient with the constant, in this case

Now form a list of the pairs of factors of -6:
1, -6
2, -3
3, -2
6, -1

Now compare the sum of each pair of factors with the coefficient of the linear term of the quadratic, in this case 1. I get that 3 + (-2) = 1. So we want to write the linear term of the quadratic as .

So




Now factor by grouping:
