Dab tsi yog Txoj Cai Tseem Ceeb? Qhov seem theorem tau teev tseg raws li nram no: Thaum ib tug polynomial a(x) muab faib los ntawm ib tug linear polynomial b(x) uas nws xoom yog x=k, cov seem yog muab los ntawm r=a(k).
Dab tsi yog qhov kev daws teeb meem ntawm Remainder Theorem?
The Remainder Theorem hais tias if a polynomial f(x) muab faib los ntawm (x - k) ces tus seem r=f(k). Nws tuaj yeem pab ua kom muaj ntau qhov kev nthuav qhia ntau dua. Lub Factor Theorem hais tias ib tug polynomial f(x) muaj ib tug yam (x - k) yog thiab xwb f(k)=0.
Dab tsi yog qhov seem theorem nrog piv txwv?
Nws yog siv los ua kom muaj ntau lub npe ntawm txhua qhov kev kawm hauv qhov zoo nkauj. Piv txwv li: yog f(a)=a3-12a2-42 muab faib los ntawm (a-3) ces qhov quotient yuav yog a2-9a-27 thiab qhov seem yog -123. Yog li, nws txaus siab rau qhov seem theorem.
Dab tsi yog qhov seem theorem rau Chav Kawm 10?
Raws li seem theorem, yog muab faib los ntawm ces, qhov seem yog muab los ntawm, Yog muab faib los, ces qhov seem yog muab los ntawm, Li no, ib tug polynomial thaum muab faib los ntawm nplooj ib seem 3 thiab thaum muab faib los ntawm nplooj ib seem 1. Yog hais tias lub polynomial muab faib los ntawm, nws tawm ib seem.
Yuav ua li cas koj pom qhov seem ntawm tus lej system?
lub tswv yim no siv qhov tseeb tias cov seem rov ua dua lawv tus kheej tom qab qee yam ntu thaum faib los ntawm tus lej. Ua ntej tshaj plaws, peb paub tias qhov seem=0 rau d – 1; qhov twg d=tus lej uas tus divisor muab faib. Yog peb faib ib los ntawm d, qhov seem tuaj yeem yog tus nqi ntawm 0 txog d-1.
