Ua raws li qhov no hauv kev txiav txim siab, koj ua li cas thiaj nrhiav tau cov nyiaj faib faib thiab cov quotient siv hluavtaws faib?

Synthetic Division los ntawm x-a

  1. 47 = 9· 5 + 2.
  2. Dividend = Quotient · Divisor + Remainder.
  3. P(x) = Q(x) · D(x) + R(x).
  4. Nqa cov coefficient ua ntej (1), muab nws nrog (2), thiab. sau cov khoom ntawd (1·2) hauv kab thib ob:
  5. Rov ua cov txheej txheem. −3 = −6.
  6. Kev daws.
  7. P(x) = Q(x) · D(x) + R.

Ib yam li ntawd, koj yuav daws qhov teeb meem sib faib li cas? Synthetic division yog lwm txoj hauv kev los faib cov polynomial los ntawm binomial x - c, qhov twg c yog qhov tsis tu ncua.

  1. Kauj Ruam 1: Teeb tsa cov khoom sib faib.
  2. Kauj Ruam 2: Nqa cov coefficient ua ntej mus rau kab hauv qab.
  3. Kauj ruam 3: Muab ntau c los ntawm tus nqi cia li sau rau ntawm kab hauv qab.
  4. Kauj ruam 4: Ntxiv cov kem tsim nyob rau hauv kauj ruam 3.

Kuj kom paub, dab tsi yog cov txheej txheem hluavtaws faib?

Synthetic faib yog shorthand, los yog shortcut, txoj kev ntawm polynomial faib nyob rau hauv cov ntaub ntawv tshwj xeeb ntawm kev faib los ntawm ib tug linear yam - thiab nws tsuas ua hauj lwm nyob rau hauv cov ntaub ntawv no. Synthetic faib feem ntau yog siv, txawm li cas los xij, tsis yog rau kev faib tawm yam tab sis nrhiav zeroes (lossis cov hauv paus hniav) ntawm polynomials. Xav paub ntxiv txog qhov no tom qab.

Dab tsi yog hluavtaws faib thiab piv txwv?

Synthetic faib yog ib txoj hauv kev luv luv ntawm kev faib cov polynomials rau cov xwm txheej tshwj xeeb ntawm kev faib los ntawm ib qho kev faib tawm uas nws tus thawj coefficient yog 1. Txhawm rau qhia txog cov txheej txheem, nco qab qhov piv txwv thaum pib ntawm ntu. Faib 2 x 3 - 3x2 + 4x + 5 2 x 3 - 3 x 2 + 4 x + 5 by x + 2 siv qhov ntev kev faib algorithm.
