# (part 3) SOS! MATH PROBLEM!?

Find the range of values of x for which (x - 1)(x - 3)>/ 15. Hence use the substitution y = x' 2', or otherwise, to solve the inequality (x' 2' - 1)(x ' 2' - 3) >/ 15.
IMPORTANT NOTE: the numbers in apostrophes ' ' are smaller in size. For example, H' 2'O is water...

IMPORTANT NOTE: the numbers in apostrophes ' ' are smaller in size. For example, H' 2'O is water and CO' 2' is carbon dioxide and O' 2' is oxygen.

P.S. >/ is actually a > with a line in the bottom of it.
