Kev daws 2nd Degree Equations ax2 + bx + c = 0 TheSquare-Root Method Siv lub hauv paus square yog tias muaj nox-term. Rau daws ax2 + bx + c = 0: 1st: Siv txoj kev square-rootmethod yog tias x-term ploj lawm. 2nd : Sim muab nws ua ob lub binomials. 3rd: siv plaub fab formula (QF).

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov kev sib npaug thib ob?

Thib ob - degree sib npaug koom nrog tsawg kawg ib qho kev sib txawv uas yog squared, los yog tsa rau lub zog ntawm ob. Ib qho ntawm cov neeg paub zoo tshaj plaws thib ob - degree sib npaug yog lubquadratic qhov twg a, b, thiab c yog qhov tsis tu ncua thiab a tsis sib npaug 0. Thib ob - degree sib npaug muaj ob txoj kev daws teeb meem: thiab.

degree ntawm kev sib npaug yog dab tsi? DEGREE NTAWM AN EQUATION . Cov degree ntawm ib kev sib npaug uas tsis muaj ntau tshaj ib qho kev sib txawv hauv txhua lub sij hawm yog tus exponent ntawm lub hwj chim siab tshaj plaws uas qhov sib txawv ntawm qhov tshwm sim hauv kev sib npaug . Cov kev sib npaug . 3x - 17 = 0. yog FIRST- DEGREE equation , txij li x tau tsa tsuas yog rau thawj lub hwj chim.

Yog li ntawd, dab tsi yog qhov thib ob degree polynomial muaj nuj nqi?

Thib ob - Degree Polynomial Function . Polynomial muaj nuj nqi uas nws daim ntawv dav dav yog f(x) = Ax2 + Bx + C, qhov twg A ≠ 0 thiab A, B, C ∈ R. A thib ob - degreepolynomial muaj nuj nqi nyob rau hauv uas tag nrho cov coefficients ntawm cov nqe lus nrog a degree tsawg dua 2 yog xoom hu ua quadratic muaj nuj nqi.

Dab tsi yog 2nd degree Trinomial?

Thib Ob Degree Polynomials . Thib ob degreepolynomials tseem hu ua quadratic polynomials . Lawv zoo li lub npe hu ua parabola. Cov khoom tsim thaum aparabola tig txog nws qhov axis ntawm symmetry yog hu ua aparaboloid, los yog parabolic reflector. Satellite phaj antennas feem ntau muaj qhov zoo li no.
