a student multiplied both sides of the equation by the expression (2x2+x−15)(2x−5)(x+3).

Was this the best thing for the student to do? If not, what should the student have done?

Just multiply both sides by (2x-5)(x+3)

The thing to watch out for is to be sure to note that 5/2 and -3 must be excluded from the domain.
