I have to factor 15x^2+2x24 How can I do this?

(5x  6)(3x + 4)
I got that by trial and error. Here's how.
The coefficients of x have to have a product ot 15. I chose 5 and 3.
The constant terms in the factors must have a product of 24. I tried 6 and 4.
The two "cross products" have to add up to two.
It worked
