The above expression is not in its simplest form, and we need to simplify it, that is what asked in the question.

Given equation,

$(9 {x}^{2} - 3x + 7) + ( - 3 {x}^{2} + 2)$

First of all, let's open the parentheses to combine the like terms for simplifying.

$9 {x}^{2} - 3x + 7 - 3 {x}^{2} + 2$

Arranging the like terms, x² with x², x with x and constant terms near to each other.

$9 {x}^{2} - 3 {x}^{2} - 3x + 7 + 2$

Simplying further,

$(9 - 3) {x}^{2} - 3x + 9$

$6 {x}^{2} - 3x + 9$

So, the correct option is C
