Question

Find the value of K for which the quadratic equation 2x²+kx+3=0 has two real equal roots.

Answer 1

Answer:

Refer to the above attachment ⬆️

Answer 2

Explanation:

See if the quadratic equation has equal roots =>

B^2 - 4AC = 0

2x^2 +kx +3

a = 2 ,b = k ,c = 3

k^2 - 4(6) = 0

k ^2 = 24

k = √24

k = √6×4

k = + or -2√6
