Question

Find the value of k for which the roots of equation 2kx-5k=(x-3)

Answer 1

if the root of this equation is (x-3) therefore, the value of x can be written as
           x-3=0
         => x=3 
Now, putting the value of x in equation 2kx-5k=0
         we get,        2k(3)-5k=0
                       => 6k-5k=0 i.e. k=1
