-3ac +3cd -8

1) In this expression,

Зас - 9cd - бас +12cd - 8 Combining like terms

-3ac +3cd -8

We might factor out (optionally)

3(cd -ac) -8

Since we can't go further, then we can either leave 3ac +3cd -8 or 3(cd -ac) -8 both expressions are equivalent.

But let's keep it with -3ac +3cd -8 that is the answer.
