I am down to three I can not figure out, help please.
subtract
(2x^4 + 9x^3 1)  (9x^2 2x +4)=

( 2X^4 + 9X^3 1 )  ( 9X^2 2X + 4 ) To remove a parenthesis with a negative sign out front, change the
sign of each term within the pa
renthesis:
2X^4 + 9X^3 1 9X^2 + 2X 4
Combine liketerms:
2X^4 + 9X^3 9X^2 +2X 5.
There were only two liketerms (1 and 4 ); i don't believe this
can be simplified further.
