what is 18x^5+3x^3+6x after it is divided by 3x? show your work. PLEASE HELP MEEE

18 x ^ 5 + 3 x ^ 3 + 6 x = 3 x ( 6 x ^ 4 + x ^ 2 + 2 )

( 18 x ^ 5 + 3 x ^ 3 + 6 x ) / 3 x = 3 x ( 6 x ^ 4 + x ^ 2 + 2 ) / 3 x =

( 3 x / 3 x ) ( 6 x ^ 4 + x ^ 2 + 2 ) =

1 * ( 6 x ^ 4 + x ^ 2 + 2 ) =

6 x ^ 4 + x ^ 2 + 2
