Question 971174
Meaning what?  You want to put into general form, like the first example?  You already learned the
method and the skills.


{{{x^2+12x=3x-18}}}
and you want in the format {{{x^2+bx+c=0}}}.  Nothing tough to do or to know.
{{{x^2+12x-3x+18=3x-3x-18+18}}}
{{{highlight(x^2+9x+18=0)}}}


That is factorable in case you really want to SOLVE it.  You can factor and then
use the Zero Product Principle.
