Piv txwv li, tus naj npawb ntawm lub sij hawm muab polynomial equation muaj ib hauv paus ntawm ib qho taw tes yog qhov ntau ntau ntawm qhov ntawd hauv paus . Txoj kev xav ntawm ntau ntau yog tseem ceeb kom suav tau kom raug yam tsis muaj qhov tshwj xeeb (piv txwv li, ob npaug keeb kwm suav ob zaug). Li no cov lus hais, "suav nrog ntau ntau ".
Tom qab ntawd, vim li cas cov hauv paus hniav polynomial tseem ceeb?
Nrhiav keeb kwm ntawm a polynomial yog ib qho heev tseem ceeb ua hauj lwm hauv Applied Maths vim hais tias muaj ntau yam teeb meem xav tau ib qho kev sib npaug sib npaug sib npaug sib npaug kom daws tau (piv txwv li: kev sib haum xeeb oscillator, LRC hluav taws xob Circuit Court, …).
Tom qab ntawd, lo lus nug yog, koj txiav txim siab ntau npaum li cas? Muaj pes tsawg zaus tus lej tshwj xeeb yog xoom rau ib lub npe polynomial. Piv txwv li, nyob rau hauv lub polynomial muaj nuj nqi f(x) = (x–3)4(x–5)(x–8)2, lub zero 3 muaj ntau ntau 4,5 ua ntau ntau 1,i8 ua ntau ntau 2. Txawm hais tias tus lej no tsuas muaj peb xoom xwb, peb hais tias nws muaj xya tus lej suav ntau ntau.
Hais txog qhov no, ntau yam ua haujlwm li cas?
Qhov zoo tshaj yog rov ua dua, uas yog, qhov xwm txheej (x−2) tshwm ob zaug. Tus naj npawb ntawm lub sij hawm ib qho tseem ceeb tshwm sim nyob rau hauv daim ntawv factored ntawm qhov sib npaug ntawm ib tug polynomial yog hu ua ntau ntau . Qhov zero cuam tshuam nrog qhov xwm txheej no, x = 2, muaj ntau ntau 2 vim qhov xwm txheej (x−2) tshwm sim ob zaug.
Yuav ua li cas koj kos ib polynomial muaj nuj nqi?
- Kauj Ruam 1: Txiav txim siab daim duab qhov kawg tus cwj pwm.
- Kauj Ruam 2: Nrhiav x-intercepts lossis xoom ntawm txoj haujlwm.
- Kauj Ruam 3: Nrhiav y-intercept ntawm txoj haujlwm.
- Kauj Ruam 4: Txiav txim siab seb puas muaj qhov sib npaug.
- Kauj ruam 5: Nrhiav tus naj npawb ntawm cov ntsiab lus tig siab tshaj plaws.
- Kauj Ruam 6: Nrhiav cov ntsiab lus ntxiv, yog tias xav tau.
- Kauj Ruam 7: Kos daim duab.

Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Vim li cas nws tseem ceeb uas peb txoj kev nkag siab txog kev tshawb fawb txog kev sib raug zoo txuas ntxiv mus?
Kev nthuav dav thiab kev loj hlob ntawm kev tshawb fawb txog kev sib raug zoo yog qhov tsim nyog vim nws pab txhawb koj txoj kev sib raug zoo thiab kev sib raug zoo nrog cov neeg hauv zej zog. Thaum koj nyob nrog cov neeg koj yuav tsum nkag siab lawv thiab social science pab koj ua li ntawd
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
Vim li cas nws tseem ceeb uas yuav tsum rov ua qhov kev sim thiab sim cov kev xav hauv ntau txoj kev?
Nws yog ib qho tseem ceeb rau cov kws tshawb fawb kom rov sim dua thaum ua qhov kev sim vim tias qhov kev txiav txim siab yuav tsum raug lees paub. Muaj tseeb vim tias cov txiaj ntsig ntawm txhua qhov kev xeem yuav tsum zoo sib xws. Lwm cov kws tshawb fawb yuav tsum tuaj yeem rov ua koj qhov kev sim thiab tau txais cov txiaj ntsig zoo sib xws. Tib txoj hauv kev los ntsuas qhov kev xav yog ua qhov kev sim
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
