Answer 2

$\Large\bf\purple{Question:}$

$\bf the \: equation : \: \: {x}^{2} - kx + 9 = 0 \\ \bf has \: equal \: roots. \: find \: the \: value \\ \bf of \: \: \: k$

$\Large\bf\purple{Answer:}$

$\large\bf{Given~that:}$

$\bf{The~quadratic~equation~has~equal~roots}$

$\bf\implies{D,~~~b^{2}-4ac=0}$

$\bf{Here,~~a=1~~~b=-k~~~c=9}$

$\bf\implies{(-k)^{2}-4(1)(9)=0}$

$\bf\implies{k-36=0}$

$\bf\implies{k={\purple{\underline{\boxed{\bf 36}}}}}$
