Yog tias ib kauj ruam hauv cov txheej txheem tshwm sim hauv=(x - 6)2, puas tuaj yeem daws qhov kev sib npaug qub los ntawm kev tsim? … Yog, qhov sib npaug tuaj yeem daws tau los ntawm kev ua haujlwm. Siv cov kab zauv muab, coj lub hauv paus square ntawm ob sab. Ob leeg 169 thiab 9 yog cov squares zoo meej, yog li sab laug dhau los ua ntxiv lossis rho tawm 13/3, uas yog qhov laj thawj.
Yuav muaj kev sib npaug plaub npaug los daws tau los ntawm kev tsim?
Tsis yog txhua qhov kev sib npaug plaub npaug tuaj yeem ua tiavlossis tuaj yeem daws tau hauv lawv daim ntawv qub uas siv cov cuab yeej square. Hauv cov xwm txheej no, peb tuaj yeem siv lwm txoj hauv kev los daws qhov sib npaug plaub npaug.
Puas yog quadratic equation a factoring?
Factoring quadratics is a method of express the quadratic equation ax2 + bx + c=0 as a product of its linear factors as (x - k)(x - h), qhov twg h, k yog cov hauv paus ntawm cov kab zauv quadratic ax2 + bx + c=0. Txoj kev no tseem hu ua txoj kev. ntawm factorization ntawm quadratic equations.
Leej twg daws thawj qhov kev sib npaug plaub npaug?
Cov qauv plaub hau npog tag nrho yog thawj zaug tau los ntawm Simon Stevin hauv 1594. Hauv 1637 René Descartes luam tawm La Géométrie muaj cov xwm txheej tshwj xeeb ntawm cov qauv plaub hau hauv daim ntawv peb paub niaj hnub no..
Leej txiv yog lej?
Archimedes yog leej txiv ntawm kev ua lej vim nws qhov tseem ceebinventions nyob rau hauv lej thiab science. Nws nyob hauv kev pabcuam ntawm Vajntxwv Hiero II ntawm Syracuse. Thaum lub sij hawm ntawd, nws tsim ntau yam inventions. Archimedes tau tsim lub tshuab rub tawm tsim los pab cov neeg tsav nkoj txav cov khoom nce thiab nqis uas hnyav.

Los ntawm cov khoom sib npaug ntawm kev sib npaug?
Cov cuab yeej sib luag ntawm kev sib luag hauv paus hais uas ob sab ntawm kev sib npaug yog tib yam. Qhov no ua rau kev txiav txim siab vim tias thaum ib yam dab tsi sib luag, nws yog tib yam ntawm ob sab. Cov cuab yeej sib luag ntawm kev sib npaug tso cai rau sab laug ntawm qhov sib npaug los ua sab xis thiab rov ua dua.
Puas txhua qhov kev sib npaug plaub npaug muaj kev daws teeb meem?
Vim li no a quadratic equation yeej ib txwm muaj ob txoj kev daws teeb meem . Factorization yog ib txoj hauv kev los daws qhov sib npaug. Cov txheej txheem dav dav ntawm factorization yog raws li hauv qab no. Txhawm rau ua kom muaj ntau qhov sib npaug ntawm daim ntawv dav dav ax2 + bx + c, ib qho yuav tsum faib nruab nrab lub sij hawm nruab nrab Lub sij hawm Nyob rau hauv logic, lub sij hawm nruab nrab yog ib lo lus uas tshwm (raws li ib qho kev kawm los yog cov lus qhia ntawm
Leej twg tsim kev sib npaug plaub npaug?
Nyob ib ncig ntawm 700AD cov kev daws teeb meem dav dav rau kev sib npaug plaub npaug, lub sijhawm no siv cov lej, tau tsim los ntawm tus lej Hindu hu ua Brahmagupta Brahmagupta Brahmagupta yog thawj tus muab cov cai los suav nrog xoom. Cov ntawv sau los ntawm Brahmagupta yog nyob rau hauv elliptic nqe lus nyob rau hauv Sanskrit, raws li yog ib qho kev xyaum nyob rau hauv Indian lej.
Txhua qhov kev sib npaug plaub npaug tuaj yeem daws tau los ntawm kev tsim?
Tsis yog txhua qhov kev sib npaug plaub npaug tuaj yeem ua tiavlossis tuaj yeem daws tau hauv lawv daim ntawv qub uas siv cov cuab yeej square. Hauv cov xwm txheej no, peb tuaj yeem siv lwm txoj hauv kev los daws qhov sib npaug plaub npaug. Puas yog txhua qhov kev sib npaug plaub npaug tuaj yeem daws tau los ntawm cov qauv quadratic?
Dab tsi yog qhov sib npaug ntawm kab rau kev sib raug zoo tsis sib haum?
Thaum nws los txog rau kev teeb tsa kev sib raug zoo tsis sib xws, nws yuav pab tau kom paub txog ob peb yam ntxwv ntawm kab zauv y=mx + b. Hauv kab zauv no, m yog sib npaug rau txoj kab nqes. Yuav ua li cas yog qhov sib npaug ntawm kev sib raug zoo?
