@jim_thompson5910 could u help

Answer 2

what do you get when you factor the denominator

Answer 3

do you know how to do that?

Answer 4

@jim_thompson5910 (x-3) (x-9)

Answer 5

so the x-3 terms will cancel

Answer 6

this means that x-3 = 0 ----> x = 3 is a removable discontinuity

Answer 7

but x - 9 = 0 ----> x = 9 is not removable

Answer 8

what are the points of discontinuity? x = 3 and x = 9

are they all removable? no, only x = 3 is removable
