Q thiab S tsis sib npaug 0
- Kauj Ruam 1: Factor ob tus lej thiab tus lej.
- Kauj Ruam 2: Sau ua ib feem.
- Kauj ruam 3: Simplify lub kev xav kev qhia.
- Kauj Ruam 4: Ntau tej yam tseem ceeb hauv tus lej thiab/lossis tus lej.
- Kauj Ruam 1: Factor ob tus lej thiab tus lej.
- Kauj Ruam 2: Sau ua ib feem.
Hais txog qhov no, koj yuav ua li cas sib npaug rational equations?
Hauv lwm lo lus koj ntau cov zauv nrog ib leeg thiab cov denominators nrog ib leeg. Koj tuaj yeem pib los ntawm kev sib npaug tus cov lus qhia thiab tom qab ntawd simplify cov lus raws li peb tau ua saum toj no lossis koj tuaj yeem pib bysimplifying lub cov lus qhia thaum nws tseem nyob rau hauv feem thiab ces ntau cov ntsiab lus seem e.g.
koj hla ntau cov lus qhia rational li cas? Cross multiplication yog txheej txheem uas peb tuaj yeem siv los daws qhov sib npaug sib npaug siv cov kauj ruam hauv qab no.
- Ua kom yooj yim qhov sib npaug kom tau txais nws hauv daim ntawv a / b = c / d, qhov twg a, b, c, thiab d yog cov lej, qhov sib txawv, lossis cov kab lus algebraic.
- Siv tus lej sib npaug los sau qhov sib npaug li ad = bc.
- daws qhov kev sib npaug tshwm sim.
Ib sab saum toj no, koj ua haujlwm ntau npaum li cas?
Thaum koj ntau ob muaj nuj nqi ua ke, koj yuav tau txais peb muaj nuj nqi raws li qhov tshwm sim, thiab qhov thib peb muaj nuj nqi yuav yog cov khoom ntawm ob tus thawj muaj nuj nqi . Piv txwv li, yog tias koj ntau f(x) andg(x), lawv cov khoom yuav yog h(x)=fg(x), or h(x)=f(x)g(x). Koj kuj tuaj yeem ntsuas cov khoom ntawm ib qho chaw tshwj xeeb.
Koj yuav daws qhov kev sib npaug sib npaug li cas?
Cov kauj ruam los daws qhov rational equation yog:
- Nrhiav tus denominator.
- Muab txhua yam los ntawm tus lej feem.
- Ua kom yooj yim.
- Tshawb xyuas cov lus teb kom paub tseeb tias tsis muaj kev daws teeb meem ntxiv.

Yuav ua li cas koj nrhiav tau undefined qhov tseem ceeb nyob rau hauv rational expressions?
Ib qho lus qhia tsis meej yog tsis tau txhais thaum tus denominator sib npaug rau xoom. Txhawm rau nrhiav cov txiaj ntsig uas ua rau qhov kev qhia tsis meej, teeb tsa tus denominator sib npaug rau xoom thiab daws qhov kev sib npaug tshwm sim. Piv txwv li: 0 7 2 3 x x − Tsis tau txhais vim hais tias tus xoom yog nyob rau hauv tus denominator
Yuav ua li cas koj multiply composite functions?
Multiplication and Composition of Functions Yuav kom muab ntau txoj haujlwm los ntawm tus lej, muab txhua qhov tso tawm los ntawm qhov ntsuas ntawd. Thaum peb coj f (g(x)), peb muab g(x) raws li cov tswv yim ntawm kev ua f. Piv txwv li, yog f (x) = 10x thiab g(x) = x + 1, ces nrhiav f (g(4)), peb nrhiav g(4) = 4 + 1 + 5, thiab ces ntsuas f (5. ) = 10(5) = 50. Example: f(x) = 2x - 2, g(x) = x2 - 8
Yuav ua li cas koj simplify rational expressions nrog multiplication?
Q thiab S tsis sib npaug 0. Kauj Ruam 1: Factor ob tus lej thiab tus lej. Kauj Ruam 2: Sau ua ib feem. Kauj Ruam 3: Ua kom yooj yim rau cov lus qhia kom meej. Kauj Ruam 4: Muab ntau yam tseem ceeb hauv tus lej thiab / lossis tus lej. Kauj Ruam 1: Factor ob tus lej thiab tus lej. Kauj Ruam 2: Sau ua ib feem
Yuav ua li cas koj nrhiav tau cov kev txwv ntawm ib tug rational qhia?
Qhov kev txwv yog tias tus denominator tsis tuaj yeem sib npaug rau xoom. Yog li hauv qhov teeb meem no, txij li 4x yog nyob rau hauv tus lej nws tsis tuaj yeem sib npaug zero. Nrhiav tag nrho cov txiaj ntsig ntawm x uas muab rau koj xoom hauv qhov denominator. Txhawm rau nrhiav cov kev txwv ntawm kev ua kom muaj nuj nqis, nrhiav qhov tseem ceeb ntawm qhov sib txawv uas ua rau tus lej sib npaug 0
Yuav ua li cas tshwm sim thaum koj muab cov khoom them nqi ze ntawm Electroscope thiab vim li cas?
Hauv cov txheej txheem induction ntawm kev them nyiaj, ib qho khoom them raug coj los ze rau tab sis tsis kov lub electroscope. Qhov no tau piav qhia los ntawm cov kev them nqi zoo li lub hauv paus ntsiab lus. Lub zais pa uas tsis zoo tiv thaiv cov hluav taws xob tsis zoo, yog li yuam kom lawv txav mus los
