化简:[-b+根号(b²-4ac)]/2a+[-b-根号(b²-4ac)]/2a(b²≥4ac)化简:[-b+根号(b²-4ac)]/2a+[-b-根号(b&#

化简:[-b+根号(b²-4ac)]/2a+[-b-根号(b²-4ac)]/2a (b²≥4ac)
化简:[-b+根号(b²-4ac)]/2a+[-b-根号(b²-4ac)]/2a (b²≥4ac)

化简:[-b+根号(b²-4ac)]/2a+[-b-根号(b²-4ac)]/2a (b²≥4ac)
[-b+根号(b²-4ac)]/2a+[-b-根号(b²-4ac)]/2a
=[-b+√(b²-4ac)-b-√(b²-4ac)]/2a
=-2b/2a
=-b/a

=-2b/2a=-b/a

－b／a
