Ua raws li qhov no hauv kev txiav txim siab, koj ua li cas thiaj nrhiav tau cov nyiaj faib faib thiab cov quotient siv hluavtaws faib?
Synthetic Division los ntawm x-a
- 47 = 9· 5 + 2.
- Dividend = Quotient · Divisor + Remainder.
- P(x) = Q(x) · D(x) + R(x).
- Nqa cov coefficient ua ntej (1), muab nws nrog (2), thiab. sau cov khoom ntawd (1·2) hauv kab thib ob:
- Rov ua cov txheej txheem. −3 = −6.
- Kev daws.
- P(x) = Q(x) · D(x) + R.
Ib yam li ntawd, koj yuav daws qhov teeb meem sib faib li cas? Synthetic division yog lwm txoj hauv kev los faib cov polynomial los ntawm binomial x - c, qhov twg c yog qhov tsis tu ncua.
- Kauj Ruam 1: Teeb tsa cov khoom sib faib.
- Kauj Ruam 2: Nqa cov coefficient ua ntej mus rau kab hauv qab.
- Kauj ruam 3: Muab ntau c los ntawm tus nqi cia li sau rau ntawm kab hauv qab.
- Kauj ruam 4: Ntxiv cov kem tsim nyob rau hauv kauj ruam 3.
Kuj kom paub, dab tsi yog cov txheej txheem hluavtaws faib?
Synthetic faib yog shorthand, los yog shortcut, txoj kev ntawm polynomial faib nyob rau hauv cov ntaub ntawv tshwj xeeb ntawm kev faib los ntawm ib tug linear yam - thiab nws tsuas ua hauj lwm nyob rau hauv cov ntaub ntawv no. Synthetic faib feem ntau yog siv, txawm li cas los xij, tsis yog rau kev faib tawm yam tab sis nrhiav zeroes (lossis cov hauv paus hniav) ntawm polynomials. Xav paub ntxiv txog qhov no tom qab.
Dab tsi yog hluavtaws faib thiab piv txwv?
Synthetic faib yog ib txoj hauv kev luv luv ntawm kev faib cov polynomials rau cov xwm txheej tshwj xeeb ntawm kev faib los ntawm ib qho kev faib tawm uas nws tus thawj coefficient yog 1. Txhawm rau qhia txog cov txheej txheem, nco qab qhov piv txwv thaum pib ntawm ntu. Faib 2 x 3 - 3x2 + 4x + 5 2 x 3 - 3 x 2 + 4 x + 5 by x + 2 siv qhov ntev kev faib algorithm.

Yuav ua li cas koj paub thaum twg yuav siv cov khoom los yog quotient txoj cai?
Kev faib ua haujlwm. Yog li, thaum twg koj pom kev sib faib ntawm ob txoj haujlwm, siv txoj cai khoom thiab nyob rau hauv rooj plaub ntawm kev faib siv txoj cai quotient. Yog tias muaj nuj nqi muaj ob qho kev sib faib thiab faib, tsuas yog siv ob txoj cai raws li. Yog tias koj pom qhov sib npaug dav nws yog ib yam zoo li, qhov twg yog qhov ua haujlwm ntawm ib leeg
Yuav siv cov tshuaj neutralization li cas los nrhiav cov concentration ntawm cov kua qaub?
Ib qho titration yog ib qho kev sim uas siv cov tshuaj tiv thaiv acid-base neutralization los txiav txim qhov tsis paub txog cov kua qaub lossis lub hauv paus. Qhov sib npaug taw tes yog mus txog thaum tus naj npawb ntawm hydrogen ions sib npaug rau tus naj npawb ntawm hydroxide ions
Yuav ua li cas koj thiaj nrhiav tau cov lej ntawm cov lej lej lossis cov lej geometric?
Cov mis rau qhov suav ntawm n cov ntsiab lus ntawm geometric ib ntus yog muab los ntawm Sn = a[(r^n - 1)/(r - 1)], qhov twg a yog thawj lub sij hawm, n yog lub sij hawm tus lej thiab r yog tus qhov piv txwv
Koj siv ntau npaum li cas los nrhiav qhov quotient?
Hauv kev sib faib cov lej uas koj muab faib yog hu ua yam; cov lus teb yog hu ua cov khoom. Hauv kev faib tus lej raug faib yog cov nyiaj faib, tus lej uas faib nws yog tus faib, thiab cov lus teb yog qhov quotient
Thaum twg koj yuav tsum siv cov haujlwm series koj siv nws li cas?
Nws yog siv los txiav txim siab cov khoom ntawm ib qho kev hloov pauv, uas yog hlau A yuav hloov lwm cov hlau B hauv kev daws yog tias A siab dua hauv koob. Kev ua yeeb yam ntawm qee cov hlau ntau dua, teev nyob rau hauv qhov kev txiav txim qis ntawm reactivity
