Question

(x^3-2x^2-11x+12)/(x-1) using long division

Answer 1

how do i solve this?

Answer 2

What single thing would you need to multiply (x-1) by to get as close as you can to the first two terms \(x^3-2x^2\)?

Answer 3

1?

Answer 4

no wait! x^2

Answer 5

Right, so you have

Answer 6

And that should have been \(-x^2-11x\)

Answer 7

So what about the next one, what would you do to get as close as you can to \(-x^2-11x\)?

Answer 8

x!

Answer 9

Exactly, so you want to add the next line in the drawing?

Answer 10

wait let me try solve this.

Answer 11

Not exactly, I almost forgot that it is a \(-x^2\), so if you subtract an 'x' you will get -2x

Answer 12

is the answer x^2 - x - 12?

Answer 13

That is what I got, nice work.

Answer 14

thank you!!

Answer 15

You're welcome.
