so please help brainlist

Answer 2

Here is your whole explanation and answer is

x = 8...

$when \: it \: is \: said \: that \: the \: zeroes \: are \: equal \: then... \\ discriminant = 0 \\ {b}^{2} - 4ac = 0 \\ {(8)}^{2} - 4(2)(k) = 0 \\ 64 - 8k = 0 \\ - 8k = - 64 \\ k = \frac{ - 64}{ - 8} \\ k = 8$
