Kyubu kusiyana ndi kusiyana cubes: malamulo a mitunduyi chulutsa Acronym

Chilinganizo kapena abridged chulutsa ulamuliro ntchito masamu, kukhala enieni - mu ajebura, chifukwa mofulumira mawerengedwe ndondomeko lalikulu mawu algebraic. Eni kuwapeza wogwila malamulo mitunduyi ajebura kwa chulutsa polynomials angapo.

Kugwiritsa mitunduyi izi okwanira ntchito njira ya mavuto osiyanasiyana masamu, ndipo zimathandizanso litsatira zosabvuta pa mawu. Malamulo amakulolani kuchita algebraic mwai ena mpheto ndi mawu, inu angatsatire pofuna kutenga mbali ya kumanzere akuti pa mbali ya dzanja lamanja, kapena kutembenuza mbali ya dzanja lamanja (kuti mawu kumanzere kwa chizindikiro ofanana).

Ndi yabwino kudziwa chilinganizo ntchito kuchepetsa chulutsa, mu kukumbukira, monga amachita ntchito pothetsa mavuto ndi maikwezhoni. Amwazisambo mitunduyi zofunika m'gulu mndandanda, ndipo dzina lawo.

Khwalala Muwerenge

Kuwerengetsa lalikulu la ndalama kuti tipeze Uwerenge lalikulu la Mauwa, kawiri chotsatira cha Mauwa wachiwiri ndi lalikulu chachiwiri. Mu ulamuliro mawonekedwe akuti kwalembedwa motere: (a + c) ² = a² + s² + 2AS.

kusiyana lofanana mbali zonse

Kuti kugwira ntchito zowerengetsa kusiyana mbali zonse, m'pofunika kuwerengera ndalama za m'bwalo la nambala yoyamba, woyamba iwiri ntchito wachiwiri (anatengedwa ndi chizindikiro zosiyana) ndi m'bwalo la nambala wachiwiri. Mu ichi ulamuliro mawonekedwe akuti motere: (a - c) ² = a² - 2AS + s².

kusiyana kwa mabwalo

Chilinganizo kusiyana kwa manambala awiri, mbali zonse, liri mankhwala Muwerenge manambala awa kusiyana awo. Mu ichi ulamuliro mawonekedwe akuti motere: a² - s² = (a + c) · (a - c).

kyubu kuchuluka

Kuwerengetsa ndalama ya mawu awiri kyubu, muyenera kuwerengera ndalama za Mauwa wa kyubu, ndi lalikulu katatu chotsatira cha Mauwa ndi chachiwiri, katatu chotsatira cha Mauwa ndi lalikulu chachiwiri ndi kyubu mawu akuti chachiwiri. Mu ichi ulamuliro mawonekedwe akuti motere: (a + c) ³ = a³ + + 3a²s 3as² s³ +.

Uwerenge cubes ndi

Malinga ndi kachitidwe, Uwerenge cubes ndi chofanana ndi mankhwala Muwerenge mawu awa nawo kusiyana mbali zonse. Mu ichi ulamuliro mawonekedwe akuti motere: a³ s³ + = (a + c) + (a² - Al + s²).

Chitsanzo. M'pofunika kuwerengera buku la chithunzi, amene anapanga ndi kuwonjezera cubes awiri. Amadziwika okha kufunika mbali.

Ngati mtengo wa zipani yaing'ono, ndiye kuchita kuwerengetsera chabe.

Ngati zotalika mbali ndi m'kukoma manambala bulky, mu nkhani iyi ndi kosavuta kutsatira mfundo ya "Uwerenge cubes", umene kwambiri wosalira kuwerengetsera lapansi.

kusiyana kyubu ndi

Mawu akuti kusiyana kiyubiki ndi: Uwerenge Mauwa wa digirii wachitatu, katatu m'bwalo la mankhwala zoipa zimene Mauwa kwachiwiri, katatu chotsatira cha Mauwa wa lalikulu la zoipa wachiwiri ndi membala yachiwiri kyubu lapansi. Mu masamu akuti kyubu kusiyana ndi motere: (a - c) ³ = a³ - 3a²s 3as² + - s³.

Kusiyana kwa cubes

cubes kusiyana chilinganizo chosiyana ndi Uwerenge cubes ndi chizindikiro chimodzi chokha. Choncho, kusiyana cubes - chilinganizo, wofanana ndi kusiyana pakati pa chiwerengero cha deta pa gawo lawo lofanana mbali ndalama. Mu masamu akuti cubes kusiyana ndi motere: ³ - ³ = (Al) ⁽² + Al + ^2).

Chitsanzo. M'pofunika kuwerengera buku la chithunzi kuti akhalabe pambuyo deducting kwa kuchuluka kwa buluu kyubu volumetric chithunzi cha mtundu wachikasu, amene alinso kyubu. Amadziwika okha kufunika mbali ya kyubu ang'ono ndi lalikulu.

Ngati mtengo wa zipani ang'onoang'ono, mawerengedwe ndi wosavuta. Ngati amayesetsa mbali ndi m'kukoma manambala kwambiri, m'pofunika kutsatira dongosolo, yakuti "Kusiyana cubes" (kapena "kyubu kusiyana") woyang'anira kwakukulu wosalira ndi mawerengedwe.
