[@MagdelenaKisting-fh3jb]

It took me a few tries but Ive got it, thank you so much Kevin you're a lifesaver!

I must say, Synthetic Division (Learned from Organic Chemistry Tutor) is a lot easier than this way of inspection. I can also understand it that way and doesn't involve so many steps.

[@basandashabalala3129]

I did the same. I got a factor using mode 3 then I synthetically divided then got the quadratic and after that just factorise the quadratic and got the 3 roots( x intercepts)

Thank you kevin i wen from doing CAPS to doing igcse and im in grade 11 and you're rally helping me catch up❤

[@nauseouskatiey]

Real😭

[@life0mpilo140]

Thank you Kevin 🎉

[@qhiki1003]

Very helpful 👍

[@kevinmathscience]

Glad it helped you :)

[@SihleSpeaks]

Tysm Kevin!❤

[@lunalunkeba945]

Thank you. I prefer this method

[@MudTshivh-zm8ql]

May you please do the synthetic method of factorising the trinomial.

[@moonman_mf]

Could you do the one with synthetic division?

i'm doing this in grade 9 in australia

[@fawaazwilliamss]

Then why you watching ?

i still dont get it

[@zaranagan2115]

so real

[@djdanzo206]

Makes 2 of us😢

[@caydenfollentine4834]

practice homie

[@esvarrstocker4339]

But kevin -2 also gives us 0, what if i used -2 in the equation to find the first x

[@watztrending_]

Sir I got -2 and 1 as my factors so which one should i choose

[@mac21278]

Both should give you the same answer

[@Weirdasf_ck]

.i used -2 and it gave me the same x-int

[@danielmangena1448]

When i use long division it gives me a remainder of - 2 why?

[@judalnaicker683]

would it be wrong to use mode 5 4

[@kevinmathscience]

Haha, silver calculator I am guessing :)
So that does give the answers (sometimes) but teachers would want to check your method of getting the answer.
You can still use it to check if you are correct.
Remember that it wont always work especially when answers are decimals etc.. They wont fit into your step.
