During his speech at the creating digital
dividends conference in october 2000, bill
gates said, “i'm a great believer that any tool
that enhances communication has profound
effects in terms of how people can learn from
each other, and how they can achieve the kind of
freedoms that they're interested in."
in what ways does algebra act as a tool to
improve communication? how does algebra
affect how people can learn from each other?

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.
