Question

If the sum of the roots of the equation x2-x=k(2x-1) is zero,then k=​

Answer 1

Answer:

Value of k is -1/2

HOPE THIS ANSWER HELPS YOU

Answer 2

x2−x=2kx−k

x2−x=2kx−kx2−(2k+1)x+K=0

x2−x=2kx−kx2−(2k+1)x+K=0sum of roots= 2K+1=0

x2−x=2kx−kx2−(2k+1)x+K=0sum of roots= 2K+1=0

              k=2−1
