Answer:

${:}\longrightarrow$
$\sf 2m^2+2m-24=0$

${:}\longrightarrow$
$\sf 2m^2-6m+4m-24=0$

${:}\longrightarrow$
$\sf 2m (m-6)+4 (m-6)=0$

${:}\longrightarrow$
$\sf (2m+4)(m-6)=0$

${:}\longrightarrow$
$\sf (2m+4)=0{\quad}or\: (m-6)=0$

${:}\longrightarrow$
$\sf 2m=-4=0 {\quad}or\: m=6$

${:}\longrightarrow$
$\sf m={\frac {4}{-2}}{\quad}or\: m=6$

${:}\longrightarrow$
$\sf m=-2 {\quad} or\:m=6$

$\therefore$
${\underline{\boxed{\bf m=-2,6}}}$
