We have to find 2 numbers such that their product will equal 

6x(-24)=-144 (which is the product of coefficient of x^2 term and the constant term)

and also their sum will equal -7(which is the coefficients of x term).

Factors of -144 are

−144,−72,−48,−36,−24,−18,−16,−12,−9,−8,−6,−4,−3,−2,−1,1,2,3,4,6,8,9,12,16,18,24,36,48,72,144

Selecting the 2 numbers from factors of 144, we get

-16 and 9

(because (-16)x9=-144 and -16+9=-7)


So now split the middle term and factorize
