Shanduko imwe: verenga fanikisheni pakukosha kwakawanda

Fanikisheni ndi x3−3x2+2\displaystyle x^{3}-3x^{2}+2. Inyorei kamwe: dinhai on C, ipapo alpha, x, second F, x kiyubhu; dinhai kubvisa, nyorai 3, ipapo alpha, x, x sikweya; dinhai kusanganisa uye nyorai 2. Zvino iverengai pa x=−1\displaystyle x=-1. Dinhai second F uye D 1, inonzi ALGB: izvi zvinokubvumira kupinza kukosha kwa x\displaystyle x, shanduko chete iri muchirevo chedu. Karukureta inobvunza x\displaystyle x: dinhai bhatani re mainasi, nyorai 1, uye dinhai enter. Mhinduro ndi −2.. Iverengai zvakare pa x=−0.5\displaystyle x=-0.5. Dinhai second F, D 1, ipapo bhatani re mainasi, 0.5, uye enter: 118\displaystyle 1\dfrac{1}{8}.
