Positive 1 actually does work.

[@kevinmathscience]

Oh yes :) Haha, so in that case, you can choose any of the numbers that work. At the end, we will get the same x intercepts :)

Is it just me or can you use both (x+1) (x-1) in 9.2???

[@kh4do]

super helpful!! but i was wondering if you could please go through the 2019 calculus section

[@sibonelosikhakhane544]

Super helpful but the block method is called "Synthetic division" it's not taught in schools anymore was taken out in like 2011 cause kids were messing it up as the teachers at my school state

[@kevinmathscience]

I see :) Yes I was not actually aware of it until some learners told me about it recently. Thank you!

[@IAMBATMAN...]

It's 2023 and we still do it

[@Khumbow_]

You made it clear on this one thank you🤝

[@Thabiso1349]

Nice joke Kevin!!! And I actually used - b div 2a... That means the jokes on me hahahaha😂😂and you got me goood

[@KgalabiMoabelo]

9.2 is giving me a different answer when i use synthetic method. i don't think your trinomial is correct

[@Kingsax2006]

No no your wrong , you most probably forgot to change the original sign of your x value before using synthetic method

[@LathithaBaninzi]

I'm getting zero for the y-value for both in 9.3 is my calculator broken or is Kevin wrong?

[@funnymemez4231]

[@Uknown450]
