Feem ntau txoj kev yooj yim tshaj plaws ntawm kev daws qhov sib npaug yog factoring Factoring txhais tau tias nrhiav cov kab lus uas tuaj yeem muab faib ua ke los muab cov lus qhia ntawm ib sab ntawm kab zauv. Yog tias qhov sib npaug plaub npaug tuaj yeem ua tau, nws raug sau ua ib yam khoom ntawm cov ntsiab lus linear.
Puas yog quadratic equation a factoring?
Factoring quadratics is a method of express the quadratic equation ax2 + bx + c=0 as a product of its linear factors as (x - k)(x - h), qhov twg h, k yog cov hauv paus ntawm cov kab zauv quadratic ax2 + bx + c=0. Txoj kev no tseem hu ua txoj kev. ntawm factorization ntawm quadratic equations.
Puas yog tag nrho cov quadratics daws tau los ntawm kev tsim?
Tsis yog, tsis yog txhua qhov kev sib npaug plaub npaug tuaj yeem daws tau los ntawm kev ua haujlwm. Qhov no yog vim tsis yog tag nrho cov kab lus quadratic, ax2 + bx + c, yog qhov ua tau.
Yuav ua li cas thiaj siv tau?
No. Txhua quadratic kab zauv muaj ob txoj kev daws teeb meem thiab tuaj yeem ua rau muaj txiaj ntsig, tab sis raws li theem ntawm qhov nyuaj nce, kev sib cais yuav tsis yooj yim thiab ib qho yuav nyiam siv cov qauv quadratic.
Dab tsi yog qhov zero factor theorem?
Koj siv lub zero factor theorem rau nrhiav cov txiaj ntsig ntawm lub quadratic tom qab koj tau ntsuas nws Piv txwv li (Los ntawm lub vev xaib saum toj no): x2 + 2x−15=0 factored yuav muab (x+3)(x+5)=0. Los ntawm lub ntsiab txhais ntawm Zero Factor Theorem, peb paub tias ib los yog ob qho tib si ntawm cov yam tseem ceeb yuav tsum sib npaug zos.
