(5w+3)(2w-6)=0
(5w+3) represents a number
(2w-6) represents another number.
When those two numbers are mutiplied together
the result equals 0. That's what
(5w+3)(2w-6)=0
tells us.
Now when two numbers are multiplied together to
equal 0, one or the other must equal 0 itself.
The question is, is it the (5w+3) that equals 0?
Or is it the (2w-6) that equals 0?
It could be either one. So there are two
possibilities:
If (5w+3) equals 0, then
5w+3 = 0
5w = -3
w = 
If (2w-6) equals 0, then
2w-6 = 0
2w = 6
w = 3
