Question 470061
<pre>
(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 = {{{-3/5}}}

If (2w-6) equals 0, then

 2w-6 = 0
   2w = 6
    w = 3
