6X^12-18X^9+18^8-54X^5-36X^3+108
you always want to start by putting like terms together. So why don't you do that first and then its really easy from there all you have to do is follow the signs(- or +) and add or subtract
so would it be
6X^12+18^8+108-18X^9-54X^5-36X^3
To simplify the expression 6x^12 - 18x^9 + 18x^8 - 54x^5 - 36x^3 + 108, start by arranging the terms in descending order of exponents:
6x^12 - 18x^9 + 18x^8 - 54x^5 - 36x^3 + 108
Next, check if any like terms can be combined. In this case, there are no like terms that can be simplified or combined.
Therefore, the simplified expression is:
6x^12 - 18x^9 + 18x^8 - 54x^5 - 36x^3 + 108
