Question

Which expression is the factored form of −1.5w+7.5 ?

Answer 1

The correct answer is C) -1.5(w-5).

Both numbers are divisible by 1.5.  Since there is a negative in the first term, we will factor that out as well.  This means we are dividing both terms by -1.5:

-1.5(     )

Taking -1.5 out of -1.5w, we have w left:

-1.5(w    )

Dividing 7.5 by -1.5, we have -5:

-1.5(w-5)
