4n² - 16n - 84 = 0
Multiply both sides by 1/4 :
n² - 4n - 21 = 0
Add 21 to both sides:
n² - 4n = 21
Complete the square by adding 4 to both sides:
n² - 4n + 4 = 25
(n - 2)² = 25
Solve for n :
n - 2 = ± √25
n - 2 = ± 5
n = 2 ± 5
Then n = 2 + 5 = 7 or n = 2 - 5 = -3.

Answer:
We have a formula for division algorithm a= bq+r (1)
a is the greatest integer between the two given integers
And b is the other integer
q is the quotient
r is the remainder
here we have a=192 and b=7 substituting values in equation (1) we get
192 = 27 *7 + 3 (2)
now substitute quotient from equation (2) in place of a that is a=27 and remainder in place of b that is b =3 in equation as below
27= 9*3 +0
we will proceed till we get remainder zero.
