Which of the following is the complete solution for the equation (x-8) (x+6)=0
1. 8 only
2. 6 only
3. 8 and -6
2 answers
It would be choice 3. The x in the first parenthesis would be 8, and in the second parenthesis 6.
When x=8 (x-8)=0 (x-8)*(x+6)=0*(x+6=0
When x=-6 (x+6)=0 (x-8)*(x+6)=(x-8)*0=0
Solutions is 8 and -6
When x=-6 (x+6)=0 (x-8)*(x+6)=(x-8)*0=0
Solutions is 8 and -6
