Was ist die Diskriminanz von: x ^ 2 - 3x +2 = 0?

Antworten:

# Delta = ± 1 #

Erläuterung:

# ax ^ 2 + bx + c = 0 #

# Delta = sqrt (b ^ 2-4 * a * c) "Diskriminanz" #

# x ^ 2-3x + 2 = 0 #

# a = 1 "; b = -3"; "c = 2 #

# Delta = sqrt ((- 3) ^ 2-4 * 1 * 2) #

# Delta = sqrt (9-8) #

# Delta = sqrt 1 #

# Delta = ± 1 #
