Excluded values

Question

(w-9)(w-3)/(w+2)(w+1) X (w+2)(w-11)/(w-9)(w-11) multiply and find excluded values

Answer 1

The excluded values are values for w that makes the denominator zero.  Those would be, -2, -2, 9 and 11.  Most of the binomials will cancel out (if they are included in both the numerator and denominator) and you will be left with:

 

(w-3)/(w+1)
