Hauv lwm lo lus, tsis yog - keeb kwm tiag imply hais tias koj cov polynomial tsis tuaj yeem muab xam rau hauv cov xwm txheej tawm ntawm qhov ntawd koj yuav tsis muaj kev cuam tshuam rau plaub fab. Factoring yog lub tswv yim zoo, yog li paub tias yuav ua li cas polynomial yam tseem ceeb heev.
Kuj paub, dab tsi yog qhov tseeb thiab tsis yog cov hauv paus hniav?
Kev xav keeb kwm tshwm sim nyob rau hauv ib tug quadratic equation thaum lub discriminant ntawm lub quadratic kab zauv - lub partunder lub square hauv paus kos npe (b2 - 4ac) - tsis zoo. Cov lej no muaj ob qho tib si tiag (the r) thiab imaginary (the si). Cov complex tus lej system muaj tag nrho cov lej r + si qhov twg r thiab s yog tiag tus lej.
Tsis tas li ntawd, dab tsi yog qhov kev daws teeb meem tiag tiag? A Tsis yog - tiag tus lej yog tus lej complex uas tuaj yeem qhia hauv daim ntawv a + bi qhov twg a thiab b yog tiag tus lej thiab kuv yog ib qho kev xav zoo sib xws. Lawv tso cai rau kev daws teeb meem rau tej equations uas tsis muaj kev daws teeb meem.
Raws li, nws txhais li cas los ntawm tsis muaj keeb kwm tiag tiag?
Case 1: Tsis muaj cag tiag Yog tias qhov kev ntxub ntxaug ntawm kev ua haujlwm plaub yog tsawg dua xoom, qhov haujlwm ntawd muaj tsis muaj cag tiag , thiab parabolait sawv cev ua tsis sib tshuam thex-axis.
Lub hauv paus tiag tiag yog dab tsi?
Muab ib qho kev sib npaug hauv ib qho kev sib txawv, a hauv paus isa tus nqi uas tuaj yeem hloov pauv rau qhov sib txawv hauv kev txiav txim tias qhov sib npaug tuav. Hauv lwm lo lus nws yog "kev daws" ntawm qhov sib npaug. Nws yog hu ua a hauv paus tiag yog nws tseem yog a tiag tus lej.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Koj puas tuaj yeem muab lub voos xwmfab hauv paus los ntawm lub hauv paus square?
Cov Khoom Muag tau nce mus rau Txoj Cai Fais Fab yog qhov tseem ceeb vim tias koj tuaj yeem siv nws los faib cov lus qhia radical. Nco ntsoov tias cov hauv paus hniav zoo ib yam - koj tuaj yeem muab cov hauv paus plaub hau nrog cov hauv paus plaub hau, lossis cov hauv paus hniav nrog lub voos xwmfab, piv txwv li. Tab sis koj tsis tuaj yeem muab lub hauv paus square thiab lub voos xwmfab hauv paus siv txoj cai no
Dab tsi yog qhov kev ntsuas ntawm lub hauv paus nyiam rau cov ntaub ntawv uas tsis yog pawg?
Lub sij hawm nruab nrab nyiam yog hais txog qhov nruab nrab, lossis ib txwm, tus nqi ntawm cov ntaub ntawv, uas feem ntau ntsuas los ntawm kev siv peb m's: txhais tau tias, nruab nrab, thiab hom. Qhov nruab nrab, nruab nrab, thiab hom yog hu ua kev ntsuas ntawm qhov nruab nrab nyiam
