$x^{2} + ( 4x) + (147)$

Step-by-step explanation:

Here, the given expression is

$x^{2} +3x +3 + (2x+134+15) - (x+5)$

Now, simplifying the brackets, we get

$x^{2} +3x +3 + (2x+134+15) - (x+5)$ = $x^{2} +3x +3 + 2x+134+15 - x -5$

Now, operate on the like terms.

= $x^{2} + ( 3x + 2x -x) + (134 + 15 + 3 -5)$

= $x^{2} + ( 4x) + (147)$

Hence, the given expression is simplified to the quadratic equation $x^{2} + ( 4x) + (147)$
