Find the values of k for which the following equations have real and e – InterviewSolution

1.	Find the values of k for which the following equations have real and equal roots:(i) x2-2k+1x+k2=0(ii) k2x2-22k-1x+4=0(iii) k+1x2-2k-1x+1=0(iv) x2+k2x+k-1+2=0
Answer» Find the values of k for which the following equations have real and equal roots: (i) $x^{2} - 2 (k + 1) x + k^{2} = 0$ (ii) $k^{2} x^{2} - 2 (2 k - 1) x + 4 = 0$ (iii) $(k + 1) x^{2} - 2 (k - 1) x + 1 = 0$ (iv) $x^{2} + k (2 x + k - 1) + 2 = 0$
