Ua kom tiav Square yog txheej txheem uas tuaj yeem siv los nrhiav qhov siab tshaj plaws lossis qhov tsawg kawg nkaus ntawm cov haujlwm plaub fab. Peb kuj tuaj yeem siv cov txheej txheem no los hloov lossis ua kom yooj yim rau daim ntawv ntawm algebraic kab zauv. Peb tuaj yeem siv nws los daws qhov sib npaug plaub npaug.
Dab tsi yog qhov zoo ntawm kev ua tiav cov square?
Ua kom tiav cov xwm txheej yog txheej txheem ntau. Lub tswv yim tseem ceeb yog hloov qhov kev sib npaug qub rau hauv ib qho ntawm daim ntawv (x + a) ^ 2=b, qhov twg a thiab b yog qhov tsis tu ncua. Qhov kom zoo dua ntawm txoj kev no yog tias nws ib txwm ua haujlwm thiab ua kom tiav square muab qee qhov kev nkag siab txog kev ua lej lej ua haujlwm ntau dua.
Thaum twg koj yuav tsum ua kom tiav lub square?
Yog koj tab tom sim nrhiav cov hauv paus ntawm kev sib npaug plaub npaug, tom qab ntawd ua tiav cov square yuav 'ib txwm ua haujlwm', hauv kev nkag siab tias nws tsis tas yuav muaj cov xwm txheej ua. rational thiab nyob rau hauv lub siab hais tias nws yuav muab rau koj complex cov hauv paus hniav yog lub quadratic lub hauv paus tsis muaj tiag.
Dab tsi yog tus qauv zoo meej square?
Yuav Ua Li Cas Sawv Cev Tus Qauv Zoo Tshaj Plaws? Tus qauv zoo meej square yog sawv cev rau hauv daim ntawv ntawm ob nqe lus xws li (a + b) 2. Kev nthuav dav ntawm cov qauv square zoo meej yog qhia raws li (a + b) 2=a2 + 2ab + b 2
txhais tau tias ua kom tiav ib square?
Ua kom tiav cov xwmfab txhais tau tias sau ib lub quadratic nyob rau hauv daim ntawv ntawm squared bracket thiab ntxiv ib qho tas mus li yogtsim nyog. Piv txwv li, xav txog x2 + 6x + 7.
