Kiera and her brother, Mitchell, are saving money to adopt a puppy. Kiera currently has $126 and plans to save an additional $14 each week. Mitchell currently has $42 and plans to save
an additional $20 each week.
How many weeks will pass before Kiera and Mitchell have the same amount of money? How
much money will they each have?

In
weeks, Kiera and Mitchell will each have $

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.
