Cov kauj ruam tseem ceeb:
- Nrhiav Qhov Tsawg Tshaj Lij Tshaj Lij (LCD) ntawm tag nrho cov denominators hauv qhov complex ib feem .
- Muab cov LCD no rau tus lej thiab tus lej ntawm qhov nyuaj feem .
- Ua kom yooj yim , yog tias tsim nyog.
Raws li, koj yuav ua li cas yooj yim ib feem ntawm ib feem?
Cov kauj ruam
- Yog tias tsim nyog, ua kom yooj yim tus lej thiab tus lej ua ib feem.
- Tig tus denominator mus nrhiav nws inverse.
- Muab cov zauv ntawm cov zauv feem ntau los ntawm qhov rov qab ntawm tus lej.
- Simplify cov feem tshiab los ntawm kev nrhiav qhov tseem ceeb tshaj plaws.
Kuj Paub, koj yuav daws qhov 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.
Kuj nug tias, txoj cai feem feem yog dab tsi?
Yog tias koj muab 0 hauv tus lej los ntawm ib tus lej ntawm txhua qhov koj tau txais 0 hauv tus lej. Nws zoo nkaus li tias muaj peev xwm sib npaug txhua tus lej. Yog li ntawd peb hais yog indeterminate, uas yog ib tug tshwj xeeb hom ntawm undefined kev qhia. B. Negative Ib feem.
Koj ua kom yooj yim cov lus qhia li cas?
Nov yog cov kauj ruam yooj yim los ua kom yooj yim rau kev qhia algebraic:
- tshem 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 nrhiav tau lub sij hawm nrog impulse thiab quab yuam?
Ib qho impulse yog sib npaug rau qhov quab yuam ntawm cov khoom lub sij hawm lub sij hawm uas lub zog no tau siv. Hauv qab no, peb muab impulse los ntawm qhov sib npaug F = ma, uas los ntawm Newton txoj cai thib ob ntawm kev txav. Kawm peb kab hauv qab no thiab nyeem cov lus qhia hauv qab lawv
Yuav ua li cas koj daws tau ntau kauj ruam sib npaug nrog variables?
Yuav kom daws tau qhov sib npaug zoo li no, koj yuav tsum xub tau txais qhov sib txawv ntawm tib sab ntawm qhov sib npaug. Ntxiv -2.5y rau ob sab kom qhov sib txawv ntawm ib sab nkaus xwb. Tam sim no cais qhov sib txawv los ntawm rho tawm 10.5 ntawm ob sab. Muab ob sab los ntawm 10 kom 0.5y ua 5y, ces faib los ntawm 5
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 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
