A kev sib npaug Ib kev sib npaug muaj tsawg kawg yog ib qho kev xav kev qhia. yog ib kev sib npaug muaj tsawg kawg yog ib qho kev xav kev qhia. daws qhov sib npaug sib npaug los ntawm clearing cov feem los ntawm multiplying ob sab ntawm lub kev sib npaug los ntawm qhov tsawg tshaj plaws denominator (LCD). Piv txwv 1: daws : 5 x − 13 = 1 x 5 x − 1 3 = 1 x.
Tom qab ntawd, koj yuav daws cov kev 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.
Qhov thib ob, koj txhais li cas los ntawm rational equation? A kev sib npaug yog ib kev sib npaug muaj tsawg kawg ib feem uas nws tus lej thiab tus lej yog polynomials, Cov zauv feem no yuav nyob ntawm ib lossis ob sab ntawm cov kev sib npaug . Ib txoj hauv kev los daws cov no kev sib npaug yog kom txo cov feem ntau mus rau ib qho denominator thiab ces daws qhov sib npaug ntawm cov zauv.
Ua raws li qhov no hauv kev xav, dab tsi yog qhov sib npaug sib npaug siv rau?
Kev sib npaug tuaj yeem yog siv rau daws ntau yam teeb meem uas cuam tshuam nrog tus nqi, sijhawm thiab ua haujlwm. Siv kev xav lus thiab kev sib npaug tuaj yeem pab koj teb cov lus nug txog kev sib txuas cov neeg ua haujlwm lossis cov tshuab ua kom tiav cov haujlwm raws sijhawm.
Yuav ua li cas koj paub yog hais tias ib tug equation yog rational?
A kev xav kev ua haujlwm yuav yog xoom ntawm tus nqi tshwj xeeb ntawm x nkaus xwb yog tus lej yog xoom ntawm qhov x thiab tus lej tsis yog xoom ntawm qhov x. Hauv lwm lo lus, rau txiav txim yog tias ib kev xav muaj nuj nqi puas yog xoom txhua yam uas peb yuav tsum tau ua yog teem tus lej sib npaug rau xoom thiab daws.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog ob txoj hauv kev los daws qhov kev sib npaug ntawm algebraically?
Thaum muab ob qhov sib npaug hauv ob qhov sib txawv, muaj ob txoj hauv kev algebraic los daws lawv. Ib qho yog kev hloov pauv, thiab lwm qhov yog tshem tawm
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
