Hey sup got stuck with nature of roots, so sad -_-

-> Show that the equation mx^2 + 5x = 5m has real and unequal roots for all real values of m

and

-> Find the values of k for which the roots of the equation

kx^2 + 2(k-3)x + k - 5 = 0 are real. Give 3 values for k for which the roots are rational.

Thanx :D
