Rau yam a trinomial hauv daim ntawv x² + bx + c, nrhiav ob tus lej, r thiab s, uas nws cov khoom yog c thiab nws cov lej yog b. Rewrite tus trinomial as x² + rx + sx + c thiab tom qab ntawd siv pawg thiab cov khoom faib rau yam lub polynomial. Qhov tshwm sim yam yuav yog (x + r) thiab (x + s).

Ib yam li ntawd, koj ua li cas rau quadratic Trinomials?

Cov ntsiab lus ntawm cov kauj ruam rau Factor Quadratic Trinomials

1. Tshem Tawm Tej Yam Tseem Ceeb yog ua tau.
2. Yog hais tias tus coefficient ntawm x² lub sij hawm yog 1, ces. x kev² + bx + c = (x + n)(x + m), qhov twg n thiab m. · Muab ntau los muab c. · Ntxiv rau muab b.
3. Yog hais tias tus coefficient ntawm x² lub sij hawm tsis yog 1, ces siv ib yam. Xav-thiab Check. Sau cov xwm txheej ntawm cov coefficient ntawm x² lub sij hawm.

Tom qab ntawd, lo lus nug yog, yog vim li cas factoring nyuaj heev? Factoring yog ib qho nyuaj tshaj qhov sib npaug vim nws tsis yog txhua yam. Ntau zaus nws suav nrog kev kwv yees lossis kev sim-thiab-kev ua yuam kev. Tsis tas li ntawd, nws tuaj yeem nyuaj dua vim qee zaum cov khoom thim rov qab thaum sib npaug. Piv txwv li, Yog tias koj tau hais kom muab ntau (x + 2) (x ²-2x + 4), koj yuav tau txais x ³+8.

Tsis tas li lo lus nug yog, dab tsi yog txoj hauv kev ntawm factoring?

Zaj lus qhia yuav suav nrog rau 6 hom kev ua haujlwm hauv qab no:

• Pawg #1: Qhov Zoo Tshaj Plaws
• Pawg #2: Pawg.
• Pawg #3: Qhov sib txawv hauv Ob Leeg.
• Pab Pawg #4: Cov txiaj ntsig lossis qhov sib txawv hauv ob lub voos xwmfab.
• Pawg #5: Trinomials.
• Pawg #6: General Trinomials.

Dab tsi yog cov yam ntxwv ntawm 36?

Cov ntsiab lus ntawm 36 : 1, 2, 3, 4, 6, 9, 12, 18, 36 . Prime factorization: 36 = 2 x 2 x 3 x 3, uas tuaj yeem sau tau 36 luas = 2 x 3². Los ntawm √ 36 = 6, tag nrho tus lej, 36 yog lub square zoo meej.
