Question

the value of k,for which the quadratic equation 4x²+4under root 3 x+ k=0 has equal roots is​

Answer 1

Answer:

K = 3

Step-by-step explanation:

here by quadratic formula

b^2 -4ac = 0 (as the roots are equal)

so putting values we get

16*3 -4×4×k = 0

48 = 16k

K = 3

Answer 2

Answer:

3

Step-by-step explanation:

if the equation has equal roots then

√b^2-4ac=0

√4√3^2-4*4*k=0

√48-16k=0

squaring both sides

48-16k=0

48=16k

k=48/16=3
