What is the inverse of the difference 1/3-1/4

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
