Vim li no a quadratic equation yeej ib txwm muaj ob txoj kev daws teeb meem . Factorization yog ib txoj hauv kev los daws qhov sib npaug. Cov txheej txheem dav dav ntawm factorization yog raws li hauv qab no. Txhawm rau ua kom muaj ntau qhov sib npaug ntawm daim ntawv dav dav ax2 + bx + c, ib qho yuav tsum faib nruab nrab lub sij hawm nruab nrab Lub sij hawm Nyob rau hauv logic, lub sij hawm nruab nrab yog ib lo lus uas tshwm (raws li ib qho kev kawm los yog cov lus qhia ntawm categorical proposition) hauv ob qho tib si qhov chaw tab sis tsis nyob rau hauv qhov xaus ntawm a categorical syllogism. Piv txwv li: Cov ntsiab lus tseem ceeb: Txhua tus txiv neej yog neeg ntiaj teb. https://en.wikipedia.org › wiki › Middle_term
