Good night teacher , i don't understand the question about lakaran graf . May I know why f(x) = 6x kuasa 2 + 11x -10 will exchange to f(x)=(3x - 2 )? . This video is already made for long time ago but i hope teacher you will see my comment at here . Lastly , I'm feel grateful for teacher making this education video cuz is helpful for my examination .
