Ib txoj hauv kev los txiav txim siab qhov siab tshaj plaws ntawm zoo thiab tsis zoo tiag keeb kwm ntawm ib tug polynomial. Txij li thaum muaj peb qhov kev hloov pauv, muaj ntau tshaj peb qhov ua tau cov cag zoo.
Ib yam li ntawd, koj tuaj yeem nug, Descartes txoj cai ntawm cov paib qhia koj li cas txog lub hauv paus tiag tiag ntawm polynomial?
Descartes ' txoj cai ntawm kos npe. Descartes ' txoj cai ntawm kos npe yog siv rau txiav txim tus lej ntawm tiag zeros a polynomial muaj nuj nqi. Nws qhia peb tias tus naj npawb ntawm qhov zoo tiag zeroes a polynomial ua haujlwm f(x) yog qhov qub lossis tsawg dua los ntawm tus lej sib npaug raws li tus lej hloov pauv hauv cov cim ntawm cov coefficients.
Tsis tas li ntawd, pes tsawg lub hauv paus ib qho kev sib npaug quadratic muaj? 2 cag
Ua li no, hom hauv paus hauv kev ua lej yog dab tsi?
Cov neeg ntxub ntxaug (EMBFQ) Cov neeg ntxub ntxaug txiav txim qhov xwm ntawm cov hauv paus hniav ntawm ib tug quadratic equation. Lo lus ' xwm' yog hais txog cov naj npawb ntawm cov hauv paus hniav tuaj yeem yog - qhov tseeb, kev xav, kev xav lossis xav txog.
Dab tsi yog cov hauv paus ntsiab lus hauv lej?
Muab ib qho kev sib npaug hauv ib qho kev sib txawv, a hauv paus yog tus nqi uas tuaj yeem hloov pauv rau qhov sib txawv hauv qhov kev txiav txim uas 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. Piv txwv li: x2-2 = 0.

Puas yog qhov tsis zoo thiab qhov zoo nqes hav tuaj yeem sib npaug?
Theorem 104: Yog hais tias ob kab muaj tib txoj kab nqes, ces cov kab yog nonverttical parallel kab. Yog hais tias ob kab yog perpendicular thiab tsis yog ib tug ntsug, ces ib tug ntawm cov kab muaj ib tug zoo nqes hav, thiab lwm yam muaj ib tug tsis zoo nqes hav. Tsis tas li ntawd, qhov tseem ceeb ntawm lawv txoj kab nqes yog qhov sib txuam
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
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
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
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
