6\100 also equals 3/50
so in turn if 50 goes into 850 exactly 17 times we can then multiply 6 by that same variable
in turn if there were 850 applicants then 102 students would be accepted into Harvard.
Factor the numerator and denominator
(x^2-x-6)/(x^2-4)
((x-3)(x+2))/((x+2)(x-2)) the (x+2)'s cancel out leaving...
(x-3)/(x-2)
