Question

(x-3)(x=5)(x-7)=0

Answer 1

I think you have a typo in your problem.

Answer 2

If you expression mean :

( x - 3 ) ( x - 5 ) ( x - 7 ) = 0

The "Zero Product Property" says:

If ( x - 3 ) ( x - 5 ) ( x - 7 ) = 0

then

( x - 3 ) = 0

or

( x - 5 ) = 0

or

( x - 7 ) = 0

Solutions :

x = 3

x = 5

and

x = 7
