You could use the quadatic equation, which is quite involved and I will not type.

(at-b)(ct-d)=
(ac)t^2 +(-ad-cb)t +(bd)
ac=2
-ad-cb=-11
bd=15

Generally, it is whole number you will be factoring in these problems, so
a or c = 2 and 1
b or d = 3 and 5
how can you arrange those number such that
-ad-cb=-11 ?
-2(3)-1(5)=-11
