Rebecca, Valerie, and Michelle were each selling pieces of pie at a bake sale. At the end of the day, the girls tried to figure out how much
pie they had left over. Rebecca had one fourth of her pie left, Valerie
had six eighths of her pie left, and Michelle had three sixths of her
pie left. How much pie did the girls have left ALTOGETHER?

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

35 is an outlier
