Expert Answer:

C o n s i d e r space t h e space g i v e n space p o l y n o m i a l
p open parentheses x close parentheses equals x squared minus open parentheses c minus a b close parentheses x minus a b c
L e t space alpha space a n d space beta space b e space t h e space z e r o e s space o f space t h e space a b o v e space e q u a t i o n

S u m space o f space t h e space z e r o e s space equals alpha plus beta equals fraction numerator negative B over denominator A end fraction equals fraction numerator negative open parentheses c minus a b close parentheses over denominator 1 end fraction equals a b minus c
P r o d u c t space o f space t h e space z e o r e s equals alpha beta equals C over A equals fraction numerator negative a b c over denominator 1 end fraction equals negative a b c
