Solve 2 - 8x + 15 <0.
Recall that the quadratic factors as:
(x - 3)(x - 5) < 0
Therefore, the intervals that must be tested are
x<3, 35.
COMPLETE
The solution set for the quadratic inequality is:
(-0,3) or (5,00)
(3,5)

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.
