First, you need to know the value of each term's exponents. Then, change their position.. (Sorry can't explain it farther, but here's an example.)

For example, your polynomial is like this. Add the exponents and change it's positions depending on it's degree. 

3a³b - 45b³ +  ab + 5b + 6 + 4a²b³ 

Therefore...
4a²b³ + 3a³b - 45b³ + ab + 5b + 6



I hope it help. ☺

lol... I just realized that the correct term is "degree" instead of "value of each term's exponents"... I hope it help anyway.. To know the degree of each term, add their exponents tho. ☺
