Txawm hais tias khib los yog txawm, ib yam polynomial ntawm qhov kev txiav txim zoo tuaj yeem muaj tus naj npawb siab kawg ntawm zeros sib npaug rau nws qhov kev txiav txim. Piv txwv li, a kub muaj peev xwm muaj raws li ntau as peb zeros , tab sis tsis muaj ntxiv. Qhov no yog lub npe hu ua lub hauv paus theorem ntawm algebra.

Ib yam li ib tus yuav nug, pes tsawg tus lej tuaj yeem ua haujlwm quintic muaj?

Fifth degree polynomials tseem hu ua quintic polynomials. Quintics muaj cov yam ntxwv no: ib mus rau tsib lub hauv paus. Zero mus rau plaub extrema.

Ib yam li ntawd, quintic Trinomial yog dab tsi? QUINTIC txhais tau tias HIGHEST DEGREE yog 5 thiab a trinomial muaj 3 nqe lus.

Cov lus nug tseem yog, puas yog 5th degree polynomial tsis muaj pes tsawg tiag?

Koj yeej yog tus xwb xoom tam sim no yog x = 2, txawm li cas los xij, qhov ntawd xoom rov qab vim nws tsuas yog ib qho tam sim no rau lub 5th degree polynomial . Qhov tseem ceeb, lub polynomial muaj 5 xoom , tag nrho yog x = 2. x 5 = 32 x 5 po keeb kwm , x = 2 and 4 non- tiag complex keeb kwm.

Yuav ua li cas koj thiaj nrhiav tau qhov zeros ntawm trinomial?

Yuav ua li cas: Muab ib tug polynomial muaj nuj nqi f, nrhiav x-intercepts los ntawm factoring

1. Teem f (x) = 0 displaystyle fleft(x ight)=0 f(x)=0.
2. Yog tias tsis muaj kev ua haujlwm polynomial tsis tau muab rau hauv daim ntawv foos: Qhia tawm ib qho xwm txheej monomial.
3. Teem txhua qhov sib npaug rau xoom thiab daws kom pom cov x- cuam tshuam.
