Antwoord: # x = 2 of x = -8 # Uitleg: # x ^ 2 + 6x - 6 = 10 # Begin met aftrekken #10# van beide kanten # x ^ 2 + 6x - 6 - 10 = 10 - 10 # # x ^ 2 + 6x - 16 = 0 # Dan factoriseer de linkerkant # (X-2) (x + 8) = 0 # Stel factoren gelijk aan #0# # x-2 = 0 of x + 8 = 0 # # x = 0 + 2 of x = 0-8 # # x = 2 of x = -8 #
