  1. Kauj Ruam 1: Factor ob tus lej thiab tus lej.
  2. Kauj Ruam 2: Sau ua ib feem.
  3. Kauj ruam 3: Simplify lub kev xav kev qhia.
  4. Kauj Ruam 4: Ntau tej yam tseem ceeb hauv tus lej thiab/lossis tus lej.
  5. Kauj Ruam 1: Factor ob tus lej thiab tus lej.
  6. 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.

  1. 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.
  2. Siv tus lej sib npaug los sau qhov sib npaug li ad = bc.
  3. 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:

  1. Nrhiav tus denominator.
  2. Muab txhua yam los ntawm tus lej feem.
  3. Ua kom yooj yim.
  4. Tshawb xyuas cov lus teb kom paub tseeb tias tsis muaj kev daws teeb meem ntxiv.
