You can put this solution on YOUR website! There are 9! = 9*8*7*6*5*4*3*2*1 = 362,880 different ways to arrange all 9 letters.
If we think of V and C as one letter, call it z, then we have the "word" "zeraious" and there are 8! = 8*7*6*5*4*3*2*1 = 40,320 ways to arrange these letters. Double this amount to account for CV to get 2*40,320 = 80,640
So there are 80,640 words where V and C are together (either as VC or CV)
So there are 362,880 - 80,640 = 282,240 different words where V and C are never adjacent to each other.
