I'm looking for PJ16, asking for a friend.
He has a basic cap, blue socks, default blockie. Maybe he grew up, I dunno, but he was one of my childhood buddies.
(Idk what points do nor do I care. I'm just here to snipe homework answers. Take them all, dude. I'm just looking for him.)

i can't see the picture : /

step-by-step explanation:

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.
