If the equation 2kx 2-4+1=0 has equal toroots then the value of k is=0
0
i want the ans for 2x2+kx+3
that is 2 yax square not 2x2
ok

2x² + kx + 3= 0 
a = 2, b = k , c = 3 
Comparing equation with ax²+ bx + c = 0, we obtain
 a = 2, b = k, c = 3...
Discriminant = b²− 4ac = (k)²− 4(2) (3) .
= k² − 24.
For equal roots, 
Discriminant = 0 
k²− 24 = 0
 k²= 24
K=√24
K=+2√6 or -2√6
1 4 1
how
√24 is in points
√24 ka ans points me atta
i dont no this problem my sister me
ok bye gnight
