The question from my textbook is...
'Add. Write the answer in descending order of the variable:
%284x%5E3%2Bx%5E2%2B3%29%2B%28x%5E3%2B2x%5E2%2B1%29'
You can only combine like terms, those that have the same exact variables raised to the same exact power.
When writing the answers in descending order, you write the term with the highest exponent to smallest exponent in order:
%284x%5E3%2Bx%5E2%2B3%29%2B%28x%5E3%2B2x%5E2%2B1%29
4x%5E3%2Bx%5E2%2B3%2Bx%5E3%2B2x%5E2%2B1
4x%5E3%2Bx%5E3%2Bx%5E2%2B2x%5E2%2B3%2B1
%284%2B1%29x%5E3%2B%281%2B2%29x%5E2%2B%283%2B1%29
5x%5E3%2B3x%5E2%2B4
Happy Calculating!!!
