Answer with detail -17= -3 - 2n 54= 17n- (-3)

We need to find the value of n in the first equation, so you would do:

- 17 = -3 - 2n

Add 3 to both sides to cancel the -3 in the side of the n variable

- 14 = -2n

Next divide to get rid of the -2 because it is multiplied by the -2

7 = n

54 = 17n - (-3)

Since you know that a negative times a negative transforms into a positive this is what it would look like:

54 = 17n + 3

Subtract 3

51 = 17n

Divide by 17 and n would be

n = 3

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.
