  1. Kauj Ruam 1: Factor ob tus lej thiab tus lej.
  2. Kauj Ruam 2: Sau ua ib feem.
  3. Kauj Ruam 3: Ua kom yooj yim tus rational 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.

Yog li ntawd, koj yuav ua li cas yooj yim sib npaug ntawm cov lus qhia txog kev xav?

Hauv lwm lo lus koj muab ntau 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 ua kom yooj yim tus kev qhia raws li peb tau ua saum toj no lossis koj tuaj yeem pib los ntawm yooj yim tus cov lus qhia thaum nws tseem nyob rau hauv feem thiab ces muab ntau ntau cov ntsiab lus seem.g.

Ib tug kuj yuav nug, ua li cas koj faib rational nthuav qhia ib kauj ruam? Kauj ruam 1: Ua tiav tag nrho cov lej thiab tus lej ntawm txhua feem. Kauj ruam 2: Hloov lub division rau a kev sib npaug kos npe thiab tig (los yog reciprocate) qhov seem tom qab kos npe faib; Qhov tseem ceeb koj yuav tsum tau muab sib npaug ntawm qhov sib npaug. Kauj ruam 3: Ncua tseg lossis txo cov feem cuam tshuam.

Ua raws li qhov no hauv kev xav, ua li cas koj ua kom yooj yim sib npaug thiab faib cov lus qhia muaj txiaj ntsig?

Rau multiply rational expressions , thawj factorall tus lej thiab tus lej thiab tshem tawm tej yam uas koj ua tau. Tom qab ntawd ntau koj tshuav dab tsi. Rau faib , yooj yim tig lub divisor (lub sij hawm koj nyob nraum kev faib los ntawm) thiab tom qab ntawd muab ntau ntau . Hauv lej-hais lus, hu ua kev sib npaug bythe reciprocal ntawm tus divisor.

Yuav ua li cas koj ua kom yooj yim multiplying algebraic feem?

Txoj kev mus muab faib ua feem yog to muab ntau ntau cov zauv ua ke, ntau cov denominators ua ke thiab ces tshem tawm yog tias tsim nyog. Txoj kev faib ib feem yog khaws thawj feem tib yam, tig lub npe faib ua a ntau thiab tig nocond feem upside down.
