Jeanette made a 3-by-3 square from tiles. She counted 9 tiles. She noticed that the one middle tile shared sides with 4 other tiles. She also noticed that each of the corner tiles of the big square shared sides with exactly 2 other tiles. Finally, she noticed that each of the middle tiles along the sides of the big square shared sides with exactly 3 other tiles. If Jeanette makes a 6-by-6 square from tiles, how many tiles will share sides with exactly 3 other tiles?

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.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

its very big question plz make it small
