Question 749514
If you multiply two numbers, or quantities together and the product is zero, then one of the factors must be zero.

First set x-6=0 and solve for x: simply add 6 to both sides, so x=6.
Then set x+8=0 and solve for x: subtract 8 from both sides, so x= -8.

Therefore, x=6 OR -8.  In either case, the product will be 0.
