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 tus rational 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.
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.

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 simplify Algebra 1 kab zauv?
Nov yog cov kauj ruam yooj yim los ua raws li kev ua kom yooj yim ntawm kev qhia algebraic: tshem tawm cov kab lus los ntawm kev sib npaug. siv cov kev cai exponent kom tshem tawm cov kab lus nyob rau hauv cov nqe lus nrog exponents. ua ke zoo li cov ntsiab lus los ntawm kev ntxiv cov coefficients. muab cov tsis tu ncua
Yuav ua li cas koj simplify lub hauv paus square los ntawm factoring?
Method 1 Simplifying a Square Root byFactoring Nkag siab txog factoring. Faib los ntawm tus lej tsawg tshaj plaws ua tau. Rewrite lub hauv paus square raws li ib tug multiplication teeb meem. Rov ua dua nrog ib tus lej ntxiv. Ua kom yooj yim los ntawm 'rub tawm' tus lej. Muab cov lej ntau ua ke yog tias muaj ntau tshaj ib
Yuav ua li cas koj simplify fractions nrog fractions thiab variables?
Cov kauj ruam tseem ceeb: Nrhiav Qhov Tsawg Tshaj Lij Tshaj Lij Tshaj Lij (LCD) ntawm tag nrho cov denominators hauv cov zauv feem. Muab cov LCD no rau tus lej thiab tus lej ntawm qhov nyuaj. Simplify, yog tias tsim nyog
Koj ua li cas cov duab rational expressions?
Txheej txheem rau Graphing ib tug Rational Function Nrhiav cov intercepts, yog tias muaj. Nrhiav cov asymptotes ntsug los ntawm kev teeb tsa tus denominator sib npaug rau xoom thiab daws. Nrhiav cov kab rov tav asymptote, yog tias muaj, siv qhov tseeb saum toj no. Cov asymptotes ntsug yuav faib cov lej kab rau hauv cheeb tsam. Sketch daim duab
