Find the value(s) of k, for which the equation kx2-kx + 1 = 0 has e

1.	Find the value(s) of k, for which the equation kx2-kx + 1 = 0 has equal roots.
Answer» For equal roots, b² -4ac=0 Here, a= k, b= -k and c=1 k² - 4(k)(1)=0 i.e. k(k- 4)=0 i.e. k=0 or k= 4 rejecting k=0, we get k= 4.

Find the value(s) of k, for which the equation kx2-kx + 1 = 0 has equal roots.

Answer»

For equal roots, b² -4ac=0

Here, a= k, b= -k and c=1

k² - 4(k)(1)=0

i.e. k(k- 4)=0

i.e. k=0 or k= 4

rejecting k=0, we get k= 4.
