Published on Nov 9, 2014. Koj yuav tau txiav txim seb puas muaj qhov sib npaug ib xal (uas yog thaum ib sib txawv sib npaug ib number), los yog nws tsis muaj daws (ob tog ntawm qhov sib npaug tsis sib npaug) los yog infinite kev daws teeb meem (ob sab ntawm qhov sib npaug yog tib yam).

Xav txog qhov no, qhov piv txwv ntawm ib qho kev daws teeb meem yog dab tsi?

Qhov no yog qhov xwm txheej ib txwm, zoo li hauv peb piv txwv qhov twg qhov sib npaug 2x + 3 = 7 muaj raws nraim ib xal , uas yog x = 2. Lwm ob kis, tsis muaj daws thiab tus naj npawb ntawm infinite kev daws teeb meem , yog cov xwm txheej oddball uas koj tsis xav tias yuav khiav mus rau ntau zaus.

Ib yam li ntawd, 0x hauv algebra yog dab tsi? Thaum peb muab ntau tus lej, txhua qhov sib txawv, ib qho kev qhia, ib qho kev sib npaug nrog xoom qhov tshwm sim yog xoom. Yog li, thaum peb muab 0 los ntawm x thiab sau nws li 0x ib , nws ua rau tsis muaj kev nkag siab vim thaum kawg cov lus teb yog xoom.

Hauv qhov no, dab tsi yog qhov kev daws teeb meem tsis kawg hauv lej?

Infinite Solutions . Thawj yog thaum peb muaj dab tsi hu ua kev daws teeb meem tsis kawg . Qhov no tshwm sim thaum txhua tus lej kev daws teeb meem . Qhov xwm txheej no txhais tau tias tsis muaj leej twg daws . Cov kev sib npaug 2 x + 3 = x + x + 3 yog ib qho piv txwv kev sib npaug uas muaj tsis kawg tus lej ntawm kev daws teeb meem.

Qhov kev sib npaug twg tsis muaj kev daws teeb meem?

Ceev faj kom tsis txhob yuam kev x = 0 nrog "tsis muaj kev daws teeb meem". Qhov kev daws x = 0 txhais tau tias cov tus nqi 0 txaus siab rau qhov sib npaug, yog li muaj kev daws teeb meem. "Tsis muaj kev daws teeb meem" txhais tau tias tsis muaj tus nqi , tsis txawm 0, uas yuav txaus siab rau qhov sib npaug.
