Question

divide
r^2-39/r-7

Answer 1

Heya there. For problems like this, you've gotta see if the numerator or denominator can factor so they can cancel each other out. If not (like in this problem) you have to use synthetic division. Do you know how to do that?

Answer 2

I dont know how to do any of it

Answer 3

That's no problem. Substitute your 'r' variable for an 'x' variable, and watch this video: http://patrickjmt.com/synthetic-division/ He describes the subject phenomenally.

Answer 4

If you need help after viewing that, feel free to ask about it.

Answer 5

Answer 6
