Question

5. Find the value of k for which the roots of the quadratic equation 2x2 +kx+8=0 will

have equal value.​

Answer 1

Answer:

K = 0

Step-by-step explanation:

for the roots to be equal coefficient of x must be zero

Answer 2

Step-by-step explanation:

Discriminant , D = k^2 - 4(8) (2) = 0

for having real and equal roots

this implies,

k = √64 = 8 Ans.
