Ukubala ama-Equation (EQN)
Ungasebenzisa inqubo elandelayo Kumodi ye-EQN ukuxazulula izibalo zelayini ngezibalo ezimbili noma ezintathu ezingaziwa, izibalo ze-quadratic, nezibalo ze-cubic.
1. Cindezela 
(EQN) ukufaka Imodi ye-EQN.
2. Kumenyu evelayo, khetha uhlobo lwesibalo.
| Ukukhetha uhlobo lwesibalo: | Cindezela lo khiye: |
|---|---|
| Izibalo zelayini ezikanyekanye ezinokungaziwa okubili |  (anX + bnY = cn) |
| Izibalo zelayini ezikanyekanye ezinokuthathu okungaziwa |  (anX + bnY + cnZ = dn) |
| Izibalo ze-quadratic |  (aX2 + bX + c = 0) |
| Izibalo ze-cubic |  (aX3 + bX2 + cX + d = 0) |
3. Sebenzisa i-kuKho-efishiyenti Editha evelayo ukufaka izimeleli ze-coefficient.
Ukuxazulula u-2x2 + x - 3 = 0, ngokwesibonelo, cindezela u- esinyathelweni 2, bese ufaka ama-coefficient alandelayo (a = 2, b = 1, c = -3): 2

3.
Ukuze ushintshe inani elifanelekile osunakho ukufaka, hambisa isikhombisi kuseli elifanele, ufake inani elisha, bese ucindezela u-.
Ukucindezela u-
kuzosula wonke ama-coefficients abe yi-zero.
Kubalulekile!
Imisebenzi elandelayo ayisekelwa yiKho-efishiyenti Editha: 
, 
(M-), 
(STO). I-Pol, i-Rec, ÷ R, kanye nezitatimende ezixubile nazo azikwazi ukufakwa kuKho-efishiyenti Editha.
4. Ngemuva kokuthi onke amanani ayindlela ofuna ngayo, cindezela u-.
Lokhu kuzobonisa isisombululo. Ukucindezela kwe- ngakunye kuzobonisa esinye isisombululo. Ukucindezela kuyilapho isisombululo sokugcina siboniswe kuzophindela kuKho-efishiyenti Editha.
Ungaskrola phakathi nezisombululo usebenzisa lo khiye 
kanye nalo-
.
Ukuphindela kuKho-efishiyenti Editha kuyilapho kuboniswe noma yisiphi isisombululo, cindezela .
Phawula
Nakuba Isibonisi Semvelo sikhethiwe, izisombululo zezibalo zelayini ezikanyekanye azibonisiwe kusetshenziswa noma yiliphi ifomu elihilela-√ .
Amanani ngeke aguqulelwe ku-engineering notation esikrinini sesisombululo.
Umayelezo ovelayo wokukwazisa uma kungenasisombululo noma uma kunezisombululo ezingenamkhawulo. Ukucindezela i- noma i- kuzophindela kuKho-efishiyenti Editha.
Ukushintsha Isethingi Lohlobo Lwesibalo Samanje
Cindezela (EQN) bese ukhetha uhlobo lwesibalo kusuka kumenyu evelayo. Ukushintsha uhlobo lwesibalo kubangela izimeleli zawo wonke ama-coefficient weKho-efishiyenti Editha ukushintshela eqandeni.
