Arranging the terms of polynomial

The terms of a polynomial are usually arranged in alphabetical order according to their letter parts, so that the exponents of the letter parts decrease from left to right. The standard term is written last.


Example 3

Arrange the polynomials.

a) [[$ -3a^2 + 6 + a^4 = a^4 -3a^2 +6 $]]​
b) ​[[$ ab +2a^3 -4b +b^2 = 2a^3 +ab +b^2 -4b $]]​
