The first term is,  5x2  its coefficient is 5.
The middle term is,  -3x  its coefficient is  - 3.
The last term, "the constant", is  -25 

Step-1: Multiply the coefficient of the first term by the constant   5 • -25 = -125 

Step-2: Find two factors of  -125  whose sum equals the coefficient of the middle term, which is   - 3.   5x2 - 3x - 25 = 0
