Simplfy. with not grouping symbols.

6x^2+9x-12
___________
2

would you factor 9x-12 first? I'm not sure

(6x^2+9x-12)/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+9x-12)/2
=3x^2 + (9/2)x - 6

Simplify the expression 5x − (3x2 + 9x).

To simplify the expression (6x^2 + 9x - 12) / 2 without grouping symbols, we can divide each term separately by 2.

First, divide 6x^2 by 2:
(6x^2) / 2 = 3x^2

Next, divide 9x by 2:
(9x) / 2 = 4.5x or (9/2)x

Finally, divide -12 by 2:
(-12) / 2 = -6

Putting it all together, the simplified expression is:
3x^2 + 4.5x - 6
