. Of the 517 graduating seniors at Brighton High School, approximately
4
5 will be attending college, and approximately
1
2 of those going to college will be attending a
state college. Which of the following is the closest estimate of the number of graduating seniors who will be
attending a state college?

9 x 8 divided by (5-3)=36

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.
