Let's know the degree 2-2x of x = 2. Find the degree 4-4x of X, the degree 3 + 6x and the degree 2-4x + 3 of X

Let's know the degree 2-2x of x = 2. Find the degree 4-4x of X, the degree 3 + 6x and the degree 2-4x + 3 of X

The square of (2-2x of x)
=The fourth power of X - the third power of 4x + 4x power
=4
The fourth power of X - the third power of 4x + the second power of 6x - 4x + 3
=(4 times of X - 3 times of 4x + 4x) + 2 (2 times of X - 2x) + 3
=4+2*2+3
=11

How to express the above formula with n
(n is the nth number)
^Denotes n

General formula: - NX ^ n

(2 times of 4x - 4x + 1) divided by (1-2x)

=1-2x
