30 POINTS WHO CAN HELP ME WIHT THIS <3 You have to put 1,2,3,4,5,6 in every row and column (NO REPEATS!), but also so you get the number in each box using +,-,x or divide.
Example: top left it says 11+. The box has two spaces, so you need two numbers that add up to 11. So the only option is 5 and 6. But you don't know which way round yet, so you must look at some other boxes first.

idk

step-by-step explanation:

use that smart brain

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.

6e14 is the answer.
