Simplifying kab lus . Ua kom yooj yim ib kev qhia tsuas yog lwm txoj hauv kev los hais daws teeb meem lej. Thaum koj ua kom yooj yim ib kev qhia , koj tab tom sim sau nws hauv txoj kev yooj yim tshaj plaws. Thaum kawg, yuav tsum tsis txhob muaj qhov ntxiv, rho tawm, sib faib, lossis faib rau sab laug ua.
Sib tham, puas yooj yim txhais tau tias yuav daws tau?
Ib pawg ntawm cov lus uas feem ntau tsis meej pem thiab siv sib hloov yog ua kom yooj yim , daws , thiab ntsuas. Kev Ntsuas: txhawm rau nrhiav tus nqi ntawm qhov kev qhia, qee zaum los ntawm kev hloov pauv ntawm qhov tseem ceeb rau cov khoom sib txawv. Ua kom yooj yim : Cov txheej txheem ntawm kev txo cov lus qhia rau ib daim ntawv luv luv lossis ib qho yooj yim ua hauj lwm nrog.
Ib yam li ntawd, ua li cas || txhais li cas hauv algebra? “|x|” ua tau txhais tau tias "tus nqi tseeb ntawm x" hauv algebra . “AB || CD" tau txhais tau tias "kab ntu AC yog sib npaug rau kab ntu BC" hauv geometry.
Tsis tas li ntawd, kuv yuav ua li cas yooj yim ib qho kev qhia?
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 simplify tus piv?
Rau ua kom yooj yim a piv , pib los ntawm kev faib tawm ob tus lej hauv qhov piv . Tom qab ntawd, nrhiav qhov tseem ceeb tshaj plaws, uas yog qhov tseem ceeb tshaj plaws uas ob tus lej hauv piv qhia. Thaum kawg, faib ob tus lej los ntawm qhov tseem ceeb tshaj plaws kom tau txais yooj yim piv.

Vim li cas kev lag luam tshuaj suav hais tias yog kev lag luam yooj yim?
Kev lag luam tshuaj siv cov khoom siv raw los tsim cov khoom lag luam qhia cov kua qaub, hauv paus, alkali thiab ntsev. Cov khoom siv feem ntau yog siv rau hauv kev tsim khoom ntawm lwm cov khoom lag luam xws li iav, chiv, roj hmab, tawv, ntawv thiab textiles. Yog li, peb tuaj yeem hais tias kev lag luam tshuaj lom neeg yog kev lag luam yooj yim
Lub Tuam Tsev txhais li cas thaum nws hais tias kuv ntseeg tias qhov zoo rau nyuj yog qhov zoo rau kev lag luam?
Lub tuam tsev txhais tau hais tias yog cov nyuj muaj kev hwm thiab kho tau zoo, lawv yuav yooj yim dua los tuav uas yuav ua rau cov txheej txheem zoo dua rau txhua tus neeg koom tes
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 ntawm daim duab yuav zoo tshaj rau kev qhia txhais tau tias rau ntau yam kev kho mob?
Ib Bar Graph. Bar graphs yog siv los sib piv cov khoom ntawm cov pab pawg sib txawv lossis taug qab kev hloov pauv sijhawm. Txawm li cas los xij, thaum sim ntsuas qhov kev hloov pauv thaum lub sijhawm, cov kab lus yog qhov zoo tshaj plaws thaum cov kev hloov pauv loj dua
Koj paub li cas thaum ib qho kev qhia nyob rau hauv nws daim ntawv yooj yim tshaj plaws?
Yog li, txhawm rau paub tias qhov kev qhia algebraic yog nyob rau hauv nws daim ntawv yooj yim tshaj plaws, koj yuav tsum ua kom paub tseeb tias koj tsis tuaj yeem faib nws ntxiv. Txij li thaum koj tuaj yeem tshem tawm (X + Y) ntawm qhov sib npaug, (X^2 - Y^2) / (X + Y) = (X - Y), uas yog daim ntawv yooj yim ntawm qhov kev qhia no
