Feem ntau, factoring yuav "undo" multiplication. Txhua lub sij hawm ntawm 10x + 5 muaj 5 as a yam 10 x + 5 = 5 (2 x + 1). Rau yam ib kev qhia los ntawm kev tshem tawm ntau yam ua raws li piv txwv 1. 3x yog qhov loj tshaj plaws yam ntawm tag nrho peb nqe lus.
Tsis tas li ntawd, koj ua li cas tawm?
Yuav Ua Li Cas Ua Tus lej
- Txiav txim siab ib qho tseem ceeb. Ib qho tseem ceeb yog 2.
- Faib txhua lub sij hawm los ntawm qhov zoo tshaj plaws thiab sau cov txiaj ntsig ntawm kev faib hauv kab lus, nrog rau qhov tshwm sim hauv ntej.
- Txiav txim siab seb koj puas tuaj yeem ua raws li lwm nqe lus. Cov ntsiab lus tseem tshuav nyob rau hauv kab lus tseem loj dhau.
- Simplify cov lus teb.
Tsis tas li ntawd, coefficients yog dab tsi? Hauv lej, a coefficient yog ib qho kev sib txuam hauv qee lub sij hawm ntawm polynomial, series, lossis ib qho kev qhia; nws feem ntau yog tus lej, tab sis tej zaum yuav yog ib qho kev qhia. Piv txwv li, yog tias y raug suav hais tias yog ib qho parameter hauv cov lus hais saum toj no, tus coefficient ntawm x yog −3y, thiab qhov tsis tu ncua coefficient yog 1.5 + y.
Yog li ntawd, dab tsi yog qhov opposite ntawm factoring?
Hauv algebra, simplifying thiab qhov tseeb kev nthuav qhia yog rov qab txheej txheem. Simplifying ib qho kev qhia feem ntau txhais tau hais tias tshem tawm ib khub ntawm cov kab lus; qhov tseeb ib qho kev qhia feem ntau txhais tau tias siv lawv.
Txoj kev factorization yog dab tsi?
Factoring . Factoring (hu ua "Factorising" hauv tebchaws Askiv) yog tus txheej txheem ntawm kev nrhiav cov xwm txheej: Factoring : Nrhiav dab tsi los sib ntxiv ua ke kom tau txais kev qhia tawm. Nws zoo li "splitting" ib qho kev qhia rau hauv kev sib npaug ntawm cov kab lus yooj yim.

Koj puas tuaj yeem piav qhia qhov xav tau traceability thiab nws qhov tseem ceeb?
Requirement Traceability yog daim ntawv qhia txog qhov yuav tsum tau ua rau kev kuaj mob. Nyob rau tib lub sijhawm, nws yog ib qho tseem ceeb kom paub tias qhov yuav tsum tau muaj qhov kev xeem tshwj xeeb tau sau rau. Cov no yog qhov tseem ceeb yog tias muaj kev hloov pauv hauv qhov yuav tsum tau ua, peb yuav tsum paub cov ntawv xeem twg uas yuav tsum tau rov sau lossis hloov kho dua
Vim li cas thiaj tseem ceeb rau qhov tseem ceeb ntawm cov kev cai?
Kev xav tau qhov tseem ceeb yog siv hauv Software tswj cov khoom lag luam los txiav txim siab tus neeg sib tw cov cai ntawm cov khoom lag luam software yuav tsum suav nrog hauv qee qhov kev tso tawm. Cov kev cai tseem ceeb tseem ceeb kom txo qis kev pheej hmoo thaum lub sij hawm kev loj hlob kom cov kev cai tseem ceeb tshaj plaws los yog muaj kev pheej hmoo siab tau ua ntej
Tus neeg twg tau soj ntsuam kev mloog lus ntawm kev sib raug zoo los ntawm kev ua ib qho kev sim uas yuav tsum muaj cov tub ntxhais kawm cov ntsiab lus los tswj cov kev mob siab rau cov ntsiab lus hauv kev tshuaj xyuas kev kawm?
Milgram Shock Experiment Ib qho ntawm cov kev tshawb fawb nto moo tshaj plaws ntawm kev mloog lus hauv kev puas siab puas ntsws tau ua los ntawm Stanley Milgram, tus kws kho mob hlwb ntawm Yale University. Nws tau ua ib qho kev sim qhia txog qhov tsis sib haum xeeb ntawm kev mloog lus rau txoj cai thiab lub siab ntawm tus kheej
Thaum cov units ntawm qhov tseem ceeb nce marginal cov nyiaj tau los ntawm ib qho tseem ceeb?
Tus nqi uas ib chav tsev ntxiv ntawm afactor ntxiv rau lub tuam txhab cov nyiaj tau los tag nrho thaum lub sij hawm hu ua marginal income product (MRP) of thefactor. Ib chav tsev ntxiv ntawm qhov tseem ceeb ntawm kev tsim khoom ntxiv rau lub tuam txhab cov nyiaj tau los hauv cov txheej txheem ob kauj ruam: ua ntej, nws nce lub tuam txhab cov khoom tsim tawm
Tshooj 404 xav tau dab tsi ntawm kev tswj hwm cov ntaub ntawv tswj xyuas sab hauv tshawb fawb lub tuam txhab pej xeem thiab piav qhia txog kev tswj hwm cov ntaub ntawv ntawm kev tswj hwm sab hauv kom ua tau raws li cov cai ntawm ntu 40
Txoj Cai Sarbanes-Oxley xav kom cov kev tswj hwm ntawm cov tuam txhab pej xeem ntsuas qhov ua tau zoo ntawm kev tswj hwm sab hauv ntawm cov neeg tawm tswv yim rau kev tshaj tawm nyiaj txiag. Tshooj 404(b) xav kom ib lub tuam txhab tuav pov hwm tus neeg soj ntsuam los ua pov thawj rau, thiab tshaj tawm txog, kev tswj xyuas kev ntsuam xyuas ntawm nws cov kev tswj hwm sab hauv
