Question

the value of k for which the following quadratic equation has equal roots x2 + x+ k​

Answer 1

answer -

k = -1/4

see I have done in this way

Answer 2

Step-by-step explanation:

Given, quadratic equation is x² + x+ k = 0

It has equal roots => b²-4ac = 0 => b² = 4ac

here, a = 1 , b = 1 , c = k

=> (1)² = 4(1)k => 1 = 4k

=> k = 1 / 4
