SOLUTION: How would I go about finding the discriminant for this: (b^2+a^2)x^2-2a^2kx+a^2k^2-a^2b^2=0 What would a, b, and c coefficients be for b^2 - 4ac for this equation? Thanks, I r

.

1)   Everybody knows the formula for discriminant  (I mean,  everybody who knows the word "discriminant").


2)   Identify coefficients at  x^2,  x  and the constant term;   then use the discriminant formula.

     ˅              ˅             ˅
  <==== Compare this to the above!

Can you now see what a, b, and c, are?
