Simplfy. with not grouping symbols.
6x^2+9x12

would you factor 9x12 first? I'm not sure

(6x^2+9x12)/2
= 3(2x^2 + 3x  4)/2
that is all the factoring that can be done,
I don't know what you mean by "grouping symbols"
perhaps they want
(6x^2+9x12)/2
=3x^2 + (9/2)x  6 
Simplify the expression 5x − (3x2 + 9x).
