Help with dividing polynomials? *EASY BEST ANSWER*?

I was sick yesterday, so I missed an algebra lesson. It was about dividing polynomials. I just want to ask people what they think the answer is for this question, so I can compare it to mine.

For the problem (20w^2 + 39w + 18) / 5w + 6, I got the answer 4w + 15 - 12.

Please tell me what you think the answer is. If this is right, just say so, but if it's wrong, please explain why.

    I used long division and found 4w+3

    -------------------------4w+3

    -----------______________

    (5w+6) | 20w^2+39w+18

    -----------+20w^2+24w----------->subtract this

    ---------------0w^2+15w+18-----39-24, bring down the 18

    -----------------------+15w+18

    ---------------0w^2+0w+0
