Question

Find the value of K for which the eq x^+5Kx+16=0has real and equal roots

Answer 1

HEY HERE IS YOUR ANSWER...

                    B^2 - 4AC =0

                    (5k)^2 - 4(1)(16) =0

                    25k^2 -64 =0

                   k^2 = 64/25

                   k = √64/25

                   k = + or - 8/5

    HOPE THIS WOULD BE HELPFUL TO YOU...
