Algebraic kab lus muaj tsawg kawg yog ib qho kev sib txawv thiab tsawg kawg yog ib qho haujlwm ( ntxiv , rho tawm, kev sib npaug , faib). Piv txwv li, 2 (x + 8y) yog ib qho kev qhia algebraic. Simplify lub algebraic qhia: Tom qab ntawd soj ntsuam cov lus qhia yooj yim rau x = 3 thiab y = -2.

Nyob rau hauv no txoj kev, dab tsi yog ib qho kev qhia algebraic hauv lej?

Algebraic qhia . Ib algebraic qhia yog a kev qhia lej uas muaj qhov sib txawv, tus lej thiab kev ua haujlwm.

Ib yam li ntawd, coefficients yog dab tsi? Hauv lej, a coefficient yog ib qho kev sib txuam hauv qee lub sij hawm ntawm polynomial, series, lossis ib qho kev qhia; nws feem ntau yog tus lej, tab sis tej zaum yuav yog ib qho kev qhia. Piv txwv li, yog tias y raug suav hais tias yog ib qho parameter hauv cov lus hais saum toj no, tus coefficient ntawm x yog −3y, thiab qhov tsis tu ncua coefficient yog 1.5 + y.

Xav txog qhov no, muaj pes tsawg hom algebraic kab lus muaj?

tsib

Yuav ua li cas koj simplify algebraic kab zauv?

Nov yog cov kauj ruam yooj yim los ua kom yooj yim rau kev qhia algebraic:

  1. tshem cov kab lus los ntawm kev sib npaug.
  2. siv cov kev cai exponent kom tshem tawm cov kab lus nyob rau hauv cov nqe lus nrog exponents.
  3. ua ke zoo li cov ntsiab lus los ntawm kev ntxiv cov coefficients.
  4. muab cov tsis tu ncua.
