Kakšne so ničle kvadratne enačbe x ^ 2 + 5x = -6?

Odgovor:

Nule na # x = -2 # in # x = -3 #

Pojasnilo:

# x ^ 2 + 5x = -6 #

#hArrcolor (bela) ("XXX") x ^ x + 5x + 6 = 0 #

#hArrcolor (bela) ("XXX") (x + 2) (x + 3) = 0 #

prav tako

#barva (bela) ("XXX") (x + 2) = 0barva (bela) ("XX") rarrcolor (bela) ("XX") x = -2 #

ali

#barva (bela) ("XXX") (x + 3) = 0barva (bela) ("XX") rarrcolor (bela) ("XX") x = -3
