Question

If the discriminant of the quadratic equation kx^2 -3√2x +4√2=0 is 14 ,the value of k is
(A) 1/4
(B) 1/4√2
(C) 1 /√2
(D) 1/3√2​

Answer 1

Answer:

value of k is 1/4√2

Step-by-step explanation:

1. discriminant is b2-4*a*c=14

2. (-3√2)2-(4*k*4√2)=14

3. (9*2)-(16*k*√2)=14

4. 18-14=16*k*√2

5. k=1/4√2
