2x(6+2+8)-4

SHOW UR WORK

32x-4

Step-by-step explanation:

1. Add the numbers.

2x(16)-4

2. Multiply the numbers.

32x-4

32x - 4

Step-by-step explanation:

2x(6+2+8)-4

Frist, we would do 6+2+8

2x(16)-4

Then, we would do 2x ⋅ 16

32x - 4

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.

what is the information provided?
