Question

Find the value of k for which the given quadrtic equation x^2-4x+k =0 has distinct real roots

Answer 1

$here \: {x}^{2} - 4x + k = 0 \\ discriminant \: = 0 \\ {b}^{2} - 4ac = 0$

$here \: a = 1 \: \: \: b = - 4 \: \: \: c = 1$

$- {4}^{2} - 4(1)(k) = 0 \\ 16 - 4k = 0 \\ - 4k = - 16 \\ k = 4$
