Nyob rau hauv algebra, ib tug quadratic muaj nuj nqi, ib tug quadratic polynomial, ib tug polynomial ntawm degree 2, los yog yooj yim ib tug quadratic, yog ib tug polynomial muaj nuj nqi nrog ib tug los yog ntau variables nyob rau hauv uas lub siab tshaj plaws -degree lub sij hawm yog qhov thib ob degree.
Puas yog quadratic polynomial yog polynomial ntawm degree 4?
A polynomial uas nws qib 2 yog hu ua quadratic polynomial. Yog li, kev xaiv (A) tsis yog cov lus teb raug. Ib tug polynomial uas nws qib 3 yog hu ua cubic polynomial yog li kev xaiv (C) kuj tsis raug. Ib tug polynomial uas nws degree yog 4 yog hu ua ib tug biquadratic polynomial.
Dab tsi yog degree ntawm kev sib npaug plaub npaug?
Qhov kev sib npaug plaub npaug kuj yog hu ua qhov sib npaug ntawm ntau yam vim nws tsuas muaj lub zog ntawm x uas tsis yog cov lej tsis zoo. Tshwj xeeb tshaj yog, nws yog qhov sib npaug thib ob-degree polynomial vim tias lub zog siab tshaj plaws yog 2. Yog li ntawd, qhov degree ntawm kev sib npaug plaub yog 2.
Yuav ua li cas polynomial yog quadratic polynomial?
A polynomial nyob rau hauv daim ntawv of ax² + bx + c qhov twg a, b thiab c yog cov lej tiag, thiab a 0 yog lub npe hu ua quadratic polynomial.
Puas yog quadratic yog degree yog 3?
Degree 2 - plaub fab. Degree 3 – cubic . Degree 4 – quartic (lossis, yog tag nrho cov ntsiab lus muaj txawm tias degree, biquadratic) Degree 5 – quintic.

Qhov twg yog qhov kev ntxub ntxaug ntawm kev sib npaug plaub npaug?
Tus neeg ntxub ntxaug yog ib feem ntawm cov qauv quadratic hauv qab lub cim square hauv paus: b²-4ac. Tus neeg ntxub ntxaug qhia peb seb puas muaj ob txoj kev daws teeb meem, ib qho kev daws teeb meem, lossis tsis muaj kev daws teeb meem . Yuav ua li cas thiaj nrhiav tau kev ntxub ntxaug ntawm kev daws teeb meem?
Puas yog txhua plaub plaub plaub plaub plaub fab?
Ib daim duab plaub yog ib qho parallelogram nrog plaub lub kaum sab xis, yog li tag nrho cov duab plaub yog kuj parallelograms thiab quadrilaterals. Ntawm qhov tod tes, tsis yog txhua qhov quadrilaterals thiab parallelograms yog cov duab plaub.
Ntawm qhov sib npaug ntawm qhov sib npaug ntawm cov reactants) thiab cov khoom) yog qhov tas li?
Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine.
Puas yog cov hauv paus ntawm kev sib npaug plaub npaug?
Roots tseem hu ua x-intercepts los yog zeros . … Yog li ntawd, kom nrhiav tau cov hauv paus hniav ntawm ib tug quadratic muaj nuj nqi, peb teem f (x)=0, thiab daws cov kab zauv, ax 2 + bx + c=0. Puas yog lub hauv paus ntawm kev sib npaug ntawm plaub npaug?
Cov tsev kawm qib siab puas yuav saib kuv cov qib kawm qib kaum ob?
Yes, lawv ua. Cov tsev kawm qib siab saib xyuas koj lub cev tag nrho ntawm kev ua haujlwm rau koj txoj haujlwm kev kawm theem siab ntawm koj qhov qhab nia nruab nrab. Tsis tas li ntawd, cov tsev kawm qib siab xav pom kev txhim kho (rau cov uas muaj qib nruab nrab mus rau qib siab) lossis sib xws (rau cov qib siab) txij qib 9 txog qib 10, thiab qib 10 txog qib 11 .
