Question

Find the value of k for for the quadratic equation 2x^2+kx+3 so they have rwo equal roots

Answer 1

Answer: +√24 or -√24

Step-by-step explanation:

Eq = 2x^2 + kx + 3

=> a = 2 , b = k & c = 3

Eq has two equal roots

=> b^2 - 4ac = 0

=> (k)^2 - 4(2)(3) = 0

=> k^2 -24 =0

=> k^2 = 24

=> k = +√24 or -√24
