How to use cross multiplication when the coefficient of quadratic term of factorization is not one

This has to be done step by step. First, you can see how many times the coefficient can be written, then you can see how many times the constant term can be written, and then you can see how to make the addition equal to the coefficient of a term. I'm not very clear about that. It depends on you to do the problem slowly

How to use cross multiplication to decompose factor when the coefficient of quadratic term is not 1
More specific,

For example: 2x square + 5x-3 = 0
2x -1
x 3
So. Then (2x-1) (x + 3) = 0
Do you understand?
