Question 204136
With  a  typical  quadratic,,,,ax^2 +bx+c=0.
.
The  Discriminant (D)  is:  (b^2 -4ac)
.
The  rule  of  Discriminants  is:
.
if  D=0,,one  solution,  curve  intercepts  the  x  axis  in  one  location
.
if  D>0,  two solutions,  curve  intercepts  the  x  axis  in  two  locations
.
if  D<0,, no  REAL  solutions,  curve  does  not  intercept  the  x  axis
.
Note  this  form  is  used  in  the  QUADRATIC FORMULA,  except as  a  square root
