Question

Which number is a solution of the inequality?

x(7 – x) > 8

Answer 1

How about 2?

Answer 2

How about 3? 4? 5?

Turns out, that inequality holds for x > 1 and x < 6 (assuming x is integer)

Answer 3

Would that be the intersection of those sets or their union?

Answer 4

Zero does not work.

Answer 5

@ ChinaGurl --> If you need just one number go with GT's 2. It works. If you want an algebraic solution, that's something else.

Answer 6

I also gave algebraic solutions assuming x is integer. :)
