Ib Kev sib npaug nrog ob kev ua haujlwm yog hu ua Ob Kauj Ruam Kev sib npaug , zoo ib kev sib npaug nrog ntau dua kev ua haujlwm los yog ntau yam kev ua haujlwm yog hu ua Multi-Step Kev sib npaug . Lub npe no yog siv vim nyob rau hauv thiaj li yuav daws tau qhov kev sib npaug koj yuav tsum siv ntau cov kauj ruam.
Ib yam li ntawd, koj tuaj yeem nug, qhov kev txiav txim ntawm kev ua lej yog dab tsi?
Qhov kev txiav txim uas yuav tsum tau ua yog abbreviatedas PEMDAS:
- Cov kab lus.
- Exponents.
- Multiplication thiab Division (los ntawm sab laug mus rau sab xis)
- Ntxiv thiab rho tawm (los ntawm sab laug mus rau sab xis)
Tom qab ntawd, lo lus nug yog, nws hu ua dab tsi thaum ob sab ntawm qhov sib npaug sib npaug? Ib kev sib npaug yog ib nqe lus lej uas yog ob nqe lus sib npaug . Kev daws ntawm ib kev sib npaug yog tus nqi uas thaum hloov pauv rau qhov sib txawv ua rau kev sib npaug ib nqe lus tseeb. Kom txav ib lub sij hawm, ntxiv nws yog oppositeto ob sab ntawm kev sib npaug.
Raws li qhov sib txawv ntawm qhov sib npaug yog dab tsi?
Zaj Lus Qhia
| Kev sib npaug | Daim ntawv General | Piv txwv |
|---|---|---|
| Tawm | y = mx + b | y = 4x + 3 |
| Quadratic | ax^2 + bx + c = 0 | 4x^2 + 3x + 1 = 0 |
| Kub | ax^3 + bx^2 + cx + d = 0 | x^3 = 0 |
| Polynomial | 5x^6 + 3x^2 + 11 = 0 |
Lub sij hawm nyob rau hauv ib qho kev sib npaug yog dab tsi?
A Lub sij hawm yog ib tus lej lossis tus lej sib txawv, lossis tus lej thiab tus lej sib npaug sib npaug ua ke. Ib qho kev nthuav qhia yog pawg ntawm cov ntsiab lus (cov ntsiab lus raug cais los ntawm + lossis − kos npe)

Dab tsi yog qhov sib npaug nrog ib lossis ntau qhov sib txawv?
Algebraic Equation - Ib qho kev sib npaug uas muaj ib lossis ntau qhov sib txawv. Algebraic Expression - Anexpression uas muaj ib lossis ntau qhov sib txawv. Coefficient- Tus naj npawb uas muab sib npaug los ntawm qhov sib txawv hauv ib lub sijhawm. Nyob rau hauv lub sij hawm 67rt, rt muaj ib coefficient ntawm 67
Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
