Given that x3 − 2x2 − x+2
= x3 − x− 2x2 +2
Grouping the 1st 2 terms together and the 2nd 2 together:
= x(x2 − 1) − 2(x2 − 1)
= (x2 − 1) (x−2)
Using the identity: a2 − b2 = (a+b) (a−b)
= (x2−12) (x−2)
= (x−1) (x+1) (x−2)

Lencho has good faith in God. Lencho's cornfield has been completely destroyed by the storm and hailstones. He thought only of one hope, the help from God. So he decided to write a letter to God asking for 100 pesos in order to resow his field. He placed a stamp on the letter and dropped into the mailbox. One of the employees, who was a postman, went to his boss and showed him the letter to God. He was inspired by the writer's faith in God. In order not to shake the writer's faith in God he decided to answer the letter. He collected money from his employees, he himself gave a part of the salary, and several friends of his were obliged to give something for an act of Charity. But he was able to collect only 70 pieces. He put the money in the envelope and addressed to Lencho.
When Lencho got the letter he did not show any bit of surprise. Instead, he became angry about getting only 70 pesos. He was sure that God could not have made a mistake nor could he have denied Lencho what he had a requested. He wrote another letter to God asking for remaining pesos and asked not to send through the mail because the post office employees are a bunch of crooks. This shows Lencho's faith in God.

The Prudential Reason for power sharing is the precautionary measure. This reason for power sharing helps to reduce the possibility of conflict between social groups.
Reserved Constituencies for minorities and women in Assemblies and Parliament is the best examples of prudential reason of power sharing in India.
The Moral Reason of power sharing is the very spirit of democracy. Here, people have a right to be consulted on how they are to be governed. Decentralisation of powers in India is the best example of moral reason of power sharing.

Let the digits at unit place be y. Let the digits at ten's place be x.
Number = 10x + y
Sum of digits of the two digits number is four times that in the unit's place. => x + y = 4y => x = 4y - y => x = 3y ......(i).
If the digits are reversed the new number will be 54 less that the original number.
Number obtained by reversing the digits = 10y + x
Number obtained by reversing the digits = 10x + y - 54 => 10y + x = 10x + y - 54 => 54 = 10x + y - 10y - x => 54 = 9x - 9y => 54 = 9(x - y) => 54/9 = x - y => 6 = x - y .........(ii).
Putting the value of x from Eq (i). in Eq (ii). => 6 = x - y => 6 = 3y - y => 6 = 2y => y = 6/2 => y = 3
Putting the value of y in Eq (ii). => 6 = x - y => 6 = x - 3 => -x = -6 - 3 => -x = -9 => x = 9
So, Number = 10x + y => 10(9) + 3 => 90 + 3 => 93
Hence, the original number is 93.
