Answer:

$\large\purple{\underline{Ꭺɳรωεɾ♬:}}$

If we solve the given Equation we get an quadratic equation that is:

$\large\boxed{{x}^{2}+{3x}-{18}={0}}$

If we start solving for x we get:

${x}^{2}+{6x}-{3x}-{18}={0}$

${x}{(x+6)}-{3}{(x+6}={0}$

${(x+6)}{(x-3)}={0}$

Therefore we get :

$\huge\boxed{\green{\underline{x = (-6) \:or\: 3}}}$
