The quadratic equation kx^2+(k-3)x+1=0 has two equal real roots.
a) Find the possible values of k.
b) Write down the values of k for which x^2+(k-3)x+k=0 has two equal real roots.
I solved a) using the quadratic formula and found k=1 or k=9, but I don't know how to do b). If I use the quadratic formula, then the values for k are the same as in a). Is that correct? Does k=1 or 9 for b) as well?
