Rau daws cov kab zauv sib npaug peb yuav ua kom hnyav siv qhov tseeb hauv qab no. Yog tias a = b ces a + c = b + c a + c = b + c rau ib qho c.

Txheej txheem los daws cov kab sib npaug

  1. Yog tias kev sib npaug muaj cov feem ntau siv qhov tsawg tshaj plaws denominator kom tshem tawm cov feem.
  2. Simplify ob sab ntawm lub kev sib npaug .

Kuj paub, dab tsi yog cov qauv rau cov kab zauv sib npaug?

Kev daws ib linear equation feem ntau txhais tau tias nrhiav tus nqi ntawm y rau tus nqi ntawm x. Yog tias kev sib npaug twb nyob rau hauv daim ntawv y = mx + b, nrog x thiab y sib txawv thiab m thiab b rational zauv, ces tus kev sib npaug tuaj yeem daws tau hauv cov ntsiab lus algebraic. 2 x yog ib qho kev qhia nrog ib lub sij hawm.

Tsis tas li ntawd, dab tsi yog qhov tsis yog kab zauv sib npaug? Tsis yog - Linear Equations Nws tsim ib txoj kab ncaj nraim los yog sawv cev rau kev sib npaug rau txoj kab ncaj nraim. Nws tsis tsim ib txoj kab ncaj nraim, tab sis tsim ib qho nkhaus. Nws tsuas muaj ib degree xwb. Los yog peb tuaj yeem txhais nws ua ib qho kev sib npaug muaj qhov kev txiav txim siab tshaj plaws ntawm 1. A nonlinear equation muaj qhov degree li 2 lossis ntau dua 2, tab sis tsis tsawg dua 2.

Ib sab saum toj no, kev sib raug zoo linear yog dab tsi?

A kev sib raug zoo ntawm ncaj proportionality uas, thaum plotted ntawm ib daim duab, traces ib txoj kab ncaj nraim. Hauv linear kev sib raug zoo , txhua qhov kev hloov pauv hauv ib qho kev hloov pauv ywj pheej yuav ua rau muaj kev hloov pauv hauv qhov sib txawv ntawm qhov sib txawv.

Dab tsi yog linear algebraic qhia?

Linear qhia yog ib algebraic qhia qhov twg lub zog ntawm qhov sib txawv yog sib npaug rau 1. Los yog peb tuaj yeem hais tias: Polynomial muaj lub zog ntawm qhov sib txawv raws li 1, hu ua Linear nthuav qhia . e.g. 2x, 3p + 8, 9s - 2z, 3d + 2c + 10e tag nrho yog cov piv txwv ntawm vim: 2x muaj qhov sib txawv x thiab nws lub zog yog 1.
