rational expressions yog multiplied thiab muab faib tib yam li cov zauv feem. Rau ntau , ua ntej pom qhov loj tshaj qhov tseem ceeb ntawm tus lej thiab tus lej. Tom ntej no, rov muab cov txheej txheem los ua cov feem sib npaug rau ib qho. Ces, ntau tej yam tseem ceeb.

Dhau ntawm qhov no, koj ua li cas thiab sib faib cov lus qhia txog kev xav?

Rau multiply rational expressions , thawj qhov tseem ceeb txhua tus lej thiab tus lej thiab tshem tawm txhua yam uas koj tuaj yeem ua tau. Ces ntau koj tshuav dab tsi. Rau faib , tsuas yog tig lub divisor (lub sij hawm koj nyob kev faib los ntawm) thiab tom qab ntawd ntau . Hauv lej-hais lus, hu ua kev sib npaug los ntawm kev sib raug zoo ntawm tus divisor.

Ib tug kuj yuav nug, dab tsi yog plaub kauj ruam rau kev sib npaug ntawm cov lus qhia? 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 muaj nuj nqis.
  • 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.

Ib sab saum toj no, koj yuav daws cov lus hais txog kev xav 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.

Dab tsi yog qhov qhia txog kev xav?

A rational qhia tsis muaj dab tsi ntau tshaj li ib feem nyob rau hauv uas tus zauv thiab/los yog tus denominator yog polynomials. Nov yog qee qhov piv txwv ntawm rational expressions.
