Question

If roots of x
+ kx + 3 = 0 are equal, then value of 'k' ​

Answer 1

Answer:

k= -4

Step-by-step explanation:

x+kx+3=0

Since, it has equal roots, x=1,

Hence,

1+k×1+3=0

1+k+3=0

4+k=0

Therefore , k= -4

Glad to help

Answer 2

x+kx+3=0

x=1

so, 1+k×1+3=0

1+k+3=0

( 1+3=4) we know that,

hence 4+k=0

k =0-4

k= -4

so, the value of k =-4
