Cov algebraic txoj kev hais txog ntau txoj kev ntawm daws ib khub ntawm kab sib npaug, nrog rau cov duab kos, hloov pauv thiab tshem tawm.
Ib yam li ntawd, koj tuaj yeem nug, algebraically txhais li cas?
Txhais ntawm algebraic . 1: Hais txog, koom nrog, lossis raws li txoj cai ntawm algebra. 2: Kev koom nrog tsuas yog tus lej kawg ntawm kev rov ua dua ntawm qhov sib ntxiv, rho tawm, sib faib, faib, rho tawm cov hauv paus, thiab nce rau lub zog algebraic equation - piv transcendental.
Ib tug kuj nug, leej twg yog leej txiv ntawm algebra? al-Khwarizmi, ua Txiv ntawm Algebra . Abu Ja'far Muhammad ibn Musa al-Khwarizmi nyob hauv Baghdad, ib ncig ntawm 780 txog 850 CE (los yog AD). Nws yog ib tug thawj sau txog algebra (siv cov lus, tsis yog ntawv).
Kuj paub, dab tsi daws rau txhais tau tias?
daws rau x txhais tau tias nrhiav tus nqi ntawm x ntawd yuav ua qhov sib npaug koj pom muaj tseeb. Xav txog qhov sib npaug no: x + 1 = 3. Yog tias koj raug nug daws nws, that yuav txhais tau tias nrhiav qee tus nqi rau x uas muab rau koj peb thaum koj ntxiv ib qho rau nws. Qhov ntawd yog dab tsi daws kev sib npaug yog txhua yam hais txog!
Txhais li cas hauv algebra?
Cov " txhais tau tias "yog qhov "nruab nrab" koj tau siv, qhov twg koj ntxiv tag nrho cov lej thiab muab faib los ntawm tus lej.

Yuav ua li cas koj daws qhov kev sib npaug ntawm tus nqi algebraically?
SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S) Kauj Ruam 1: Cais tawm tus nqi tseeb. Kauj ruam 2: Teem kom muaj nuj nqis nyob rau hauv qhov tseeb tus nqi notation sib npaug rau + thiab - qhov ntau nyob rau sab nraud ntawm qhov sib npaug. Kauj Ruam 3: daws qhov tsis paub hauv ob qho tib si sib npaug. Kauj Ruam 4: Tshawb xyuas koj cov lus teb analytically lossis graphically
Qhov twg yog acidic ntau dua ib qho kev daws ntawm pH 2 lossis kev daws ntawm pH 6?
Kev piav qhia: pH yog qhov ntsuas ntawm acidity lossis alkalinity ntawm cov tshuaj. concentration siab dua yog acidity. Yog li ib qho kev daws ntawm pH = 2 yog acidic ntau dua li ntawm pH = 6 los ntawm qhov zoo ntawm 10000
Yuav ua li cas koj pom cov hauv paus hniav ntawm ib qho kev sib npaug algebraically?
Cov hauv paus hniav ntawm ib qho kev sib npaug plaub yog muab los ntawm: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Sau lub quadratic nyob rau hauv daim ntawv ntawm ax^2 + bx + c = 0. Yog hais tias qhov sib npaug yog nyob rau hauv daim ntawv y = ax^2 + bx + c, tsuas yog hloov lub y nrog 0. Qhov no yog ua li cas vim lub hauv paus ntawm lub equation yog cov nqi uas qhov y axis sib npaug rau 0
Koj yuav daws tau qhov system ntawm linear equations algebraically li cas?
Siv kev tshem tawm los daws cov kev daws teeb meem hauv ob qhov sib npaug: x + 3y = 4 thiab 2x + 5y = 5. x = −5, y = 3. Muab txhua lo lus hauv thawj kab zauv los ntawm –2 (koj tau txais –2x – 6y = –8) thiab tom qab ntawd ntxiv cov ntsiab lus hauv ob qhov sib npaug ua ke. Tam sim no daws -y = -3 rau y, thiab koj tau y = 3
Dab tsi yog ob txoj hauv kev los daws qhov kev sib npaug ntawm algebraically?
Thaum muab ob qhov sib npaug hauv ob qhov sib txawv, muaj ob txoj hauv kev algebraic los daws lawv. Ib qho yog kev hloov pauv, thiab lwm qhov yog tshem tawm
