Answer:
C
Step-by-step explanation:
OK to start off I'm pretty sure you meant to put (3x^2) rather than 3x^3, but I'll just ignore that part, so we first want to remove the parentheses and we add 6x^2-5x+3+3x^2+7x-8 so, we simplify and get: 9x^2+2x-5.
Which is C.

We have given a polynomial; [tex](6x^2-5x+3)+(3x^2+7x-8 )\\\\[/tex] Hence, the correct answer is C. [tex]9x^2+2x-5[/tex].
What is a polynomial?
They are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.
We have given a polynomial;
[tex](6x^2-5x+3)+(3x^2+7x-8 )\\\\[/tex]
By adding the like terms
[tex]6x^2-5x+3+3x^2+7x-8 \\\\ 6x^2+3x^2 -5x+7x+3-8[/tex]
so, we simplify and get:
[tex]9x^2+2x-5[/tex].
Hence, the correct answer is C. [tex]9x^2+2x-5[/tex].
