SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)
- Kauj ruam 1: cais cov kiag li tus nqi qhia.
- Kauj ruam 2: Teem kom muaj nuj nqis hauv lub kiag li tus nqi sau sib npaug rau + thiab - qhov ntau ntawm sab nraud ntawm qhov sib npaug.
- Kauj Ruam 3: daws rau qhov tsis paub hauv ob qho tib si kev sib npaug .
- Kauj Ruam 4: Tshawb xyuas koj cov lus teb analytically lossis graphically.
Ua li no, koj ua li cas thiaj nrhiav tau tus nqi tiag?
Cov tus nqi kiag ntawm tus lej yog tus lej deb ntawm xoom, uas yuav ib txwm ua qhov zoo tus nqi . Rau nrhiav tus tus nqi kiag ntawm ib tus lej, poob qhov tsis zoo yog tias muaj ib qho los ua tus lej zoo. Piv txwv li, qhov tsis zoo 4 yuav dhau los ua 4.
Tom qab ntawd, lo lus nug yog, dab tsi yog lub cim rau tus nqi tiag? Cov cim rau tus nqi kiag yog ob txoj kab ncaj nraim nyob ib puag ncig tus lej lossis kev qhia uas koj xav qhia tus nqi kiag . |6| = 6 txhais tau tias tus nqi kiag 6 yog 6.
Kuj kom paub, dab tsi yog cov cai rau tus nqi tiag?
Thaum peb muab lub tus nqi kiag ntawm tus lej, peb ib txwm xaus nrog tus lej zoo (lossis xoom). Txawm hais tias qhov kev tawm tswv yim yog qhov zoo lossis tsis zoo (lossis xoom), cov zis yog ib txwm zoo (lossis xoom). Piv txwv li, | 3 | = 3, thiab | –3 | = 3 too.
Koj yuav daws tau qhov system ntawm kev sib npaug li cas?
Ua raws li cov kauj ruam los daws qhov teeb meem
- Kauj Ruam 1: Muab tag nrho thawj qhov sib npaug los ntawm 2.
- Kauj Ruam 2: Rov sau cov txheej txheem ntawm kev sib npaug, hloov thawj qhov sib npaug nrog cov kab zauv tshiab.
- Kauj Ruam 3: Ntxiv qhov sib npaug.
- Kauj ruam 4: daws rau x.
- Kauj Ruam 5: Nrhiav y-tus nqi los ntawm kev hloov hauv 3 rau x hauv qhov sib npaug.

Yuav ua li cas cov tsev neeg ntawm kev ua haujlwm tsis thiab cov lus piav qhia ntawm cov duab cuam tshuam?
Cov tsev neeg muaj nuj nqi yog pab pawg ua haujlwm nrog qhov zoo sib xws uas ua rau lawv yooj yim rau kev teeb tsa thaum koj paub txog kev ua haujlwm ntawm niam txiv, qhov piv txwv yooj yim tshaj plaws ntawm daim ntawv. Ib qho parameter yog qhov sib txawv hauv cov kab zauv dav dav uas siv rau ntawm tus nqi tshwj xeeb txhawm rau tsim ib qho kev sib npaug
Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Koj yuav txiav txim siab li cas yog tias qhov tsis sib xws tsis muaj kev daws teeb meem?
Cais tawm tus nqi tseeb ntawm sab laug ntawm qhov tsis sib xws. Yog tias tus lej ntawm sab nraud ntawm qhov tsis sib xws yog qhov tsis zoo, koj qhov kev sib npaug tsis muaj kev daws teeb meem lossis tag nrho cov lej tiag tiag li kev daws teeb meem. Siv cov cim ntawm txhua sab ntawm koj qhov tsis sib xws los txiav txim siab qhov twg ntawm cov xwm txheej no tuav
Thaum muab piv cov qauv sau rau ib tus neeg raug liam cov ntaub ntawv lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub tshaj kaum ob lub hlis?
Thaum piv cov qauv sau rau tus neeg raug liam? cov ntaub ntawv, lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub ntau tshaj rau rau kaum ob lub hlis. Tus lej txaus ntawm tus qauv yog qhov tseem ceeb rau kev txiav txim siab qhov tshwm sim ntawm kev sib piv
Yuav ua li cas koj thiaj paub yog tias tus nqi tsis sib xws tsis muaj kev daws teeb meem?
Okay, yog tias qhov tseem ceeb tshaj plaws yeej ib txwm zoo lossis xoom tsis muaj txoj hauv kev uas lawv tuaj yeem tsawg dua lossis sib npaug rau tus lej tsis zoo. Yog li ntawd, tsis muaj kev daws teeb meem rau ob qho no. Hauv qhov no yog tias tus nqi tiag tiag yog qhov zoo lossis xoom ces nws yuav nco ntsoov ntau dua lossis sib npaug rau tus lej tsis zoo
