uas yog ib qho piv txwv ntawm kev qhia algebraic? Ib algebraic qhia yog kev sib xyaw ua ke ntawm cov lej tsis tu ncua, hloov pauv, tus lej thiab algebraic kev ua haujlwm xws li ntxiv, rho tawm, sib faib thiab faib. 5x, x + y, x - 3 thiab ntau dua yog piv txwv ntawm algebraic qhia . Ib qhov tsis tu ncua yog ib pawg ntawm cov lej.

Dhau li ntawm no, koj sau ib qho kev qhia hauv lej li cas?

Ib piv txwv ntawm a kev qhia lej nrog rau qhov sib txawv yog 2x + 3. Txhua qhov sib txawv yuav tsum muaj cov coefficient, tus lej uas muab ntau dua los ntawm qhov sib txawv. Hauv kev qhia 2 x + 3, coefficient ntawm x yog tus lej 2, thiab nws txhais tau tias 2 x ntxiv 3.

Coefficients yog dab tsi?
