Long Division is Long!

Sometimes dividing polynomials can be very long! A whole page for one problem! Part of what makes it so hard is that a single division problem may require you to use all these skills:
  • adding and subtracting integers

  • adding and subtracting fractions

  • adding and subtracting algebraic terms

  • multiplying integers and algebraic terms

  • dividing integers and algebraic terms

That's a lot to keep track of!

I have two bits of advice for you:

(1) Take it slowly; one step at a time. Focus on a single skill (listed above) at a time.

(2) Remember Sysiphus! Don't give up. Keep at it and you will succeed.

If you need a little review of what we did in class today you can find it here

Cheers,
Mr. K.

I'm doing Exercise 8 right now and I was wondering if anyone would be able to tell me...when you have a remainder, when do you write it as a fraction and when do you just write R # beside the quotient? OR are both ok?

Sir, I'm doing Exercise 8 at this moment and I'm having a hard time doing number 14..

Hey John d.
For # 14...

take the formula for volume of a cone (which im pretty sure is pi times radius squared times height, divided by three) and just use that and go backwards and that should give you the radius. =)
