Find the valueofk for which the quadratic equationhas equal roots.
Both 1 and 2
Either 1 or 2
The standard quadratic equation is If the roots are real and equal then D=0 If the roots are real and unequal then D>0 If the roots are real and imaginary then D<0 By comparing the standard equation with given equation, Therefore,
