Cov npe nram qab no yog muab rau polynomials Raws li lawv cov degree: Qib 4 - quartic (lossis, yog tias tag nrho nqe lus muaj txawm degree, biquadratic) Qib 5 - quintic. Qib 6 - sextic (los yog tsawg dua, hexic)

Hais txog qhov no, dab tsi yog polynomial nrog 5 nqe lus hu ua?

Koj hu ib qho kev qhia nrog ib leeg lub sij hawm monomial, ib qho kev nthuav qhia nrog ob nqe lus yog binomial, thiab ib qho kev qhia nrog peb nqe lus yog trinomial. Ib qho kev nthuav qhia nrog ntau tshaj peb nqe lus yog lub npe yooj yim los ntawm nws tus lej ntawm nqe lus . Piv txwv li a polynomial nrog tsib nqe lus yog hu ua ib tsib- lub sij hawm polynomial.

Qhov thib ob, lub ntsiab lus tseem ceeb ntawm polynomial yog dab tsi? Hauv ib polynomial , cov thawj lub sij hawm yog cov lub sij hawm nrog lub zog siab tshaj x. Piv txwv li, lub thawj lub sij hawm 7 + x² - 3x + 2 Cov thawj coefficient ntawm polynomial yog cov coefficient ntawm thawj lub sij hawm.

Kuj yuav paub yog, dab tsi yog ib tug polynomial hu ua thaum nws muaj 4 nqe lus?

A polynomial ntawm plaub nqe lus yog qee zaum hu ua lub quadrinomial, tab sis muaj tiag tiag tsis xav tau xws li lus . Tias yog vim tus naj npawb ntawm nqe lus hauv a polynomial tsis tseem ceeb.

Qhov degree ntawm 5 yog dab tsi?

Qib ntawm ib tug polynomial. muaj peb nqe lus. Thawj lub sij hawm muaj a qib 5 (cov sum ntawm lub hwj chim 2 thiab 3), lub sij hawm thib ob muaj a degree ntawm 1, thiab lub sijhawm kawg muaj a degree ntawm 0. Yog li ntawd, lub polynomial muaj a qib 5 , uas yog qhov siab tshaj degree ntawm tej lub sij hawm.
