6. Make a conjecture about the sum of primes based on the following pattern: 4=2+2
6 = 3+3
8 = 3 + 5
10 = 3 +7
12 = 5 + 7

it should be a and d. lmk if i'm wrong xd

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.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:
