Antwoord:
Nullen bij # X = -2 # en # X = -3 #
Uitleg:
# X ^ 2 + 5x = -6 #
#hArrcolor (wit) ("XXX") x ^ x + 5x + 6 = 0 #
#hArrcolor (wit) ("XXX") (x + 2) (x + 3) = 0 #
een van beide
#color (wit) ("XXX") (x + 2) = 0color (wit) ("XX") rarrcolor (wit) ("XX") x = -2 #
of
#color (wit) ("XXX") (x + 3) = 0color (wit) ("XX") rarrcolor (wit) ("XX") x = -3 #
