Question

find value of k for which the quadratic equation ​

Answer 1

Answer:

After that we can apply the direct formula and find the value of \[{b^2} - 4ac\] for the given quadratic equation and equate that with zero. Now we had to solve equation 3 to get the value of k. Hence, for the value of k = 5 or – 3, the roots of the given quadratic equation will be equal

Answer 2

Answer:

It has given that the quadratic equation has equal roots. So this means the determinants will be zero. i.e. b2−4ac

= 0, where a, b and c are the coefficients of x2

, x and constant terms of the given quadratic equation in the question. And solve the quadratic equation of k to get the required value of k.
