Ethan, Farah, and Michael invested 427 000$ 671 000$ and 305000$ respectively and decided to share the ratio in their investments. After a few years, they sold the property for $1 897 500. Find the amount of profit each of them received.

$427 000 + $671 000 + $305 000 = $1 403 000

Profit= $1 897 500 - $1 403 000 = $494 000

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.
