Answer 1

Answer:f

( x ) = x ,  g ( x ) = x 3 − 1 f ( x ) = x 4 + x 3 − 11 x 2 − 5 x + 30 ,  g ( x ) = 2 x − 2 f ( x ) = x 2 ,  g ( x ) = 7 x − 1

in short ways the answer is  7 x − 1

Answer 2

Hence , the sum is $11x^2-8x-14$.

WHAT IS A POLYNOMIAL

In mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

How to Solve?

Given , we need to add $2x^2-8x-6$ and $9x^2-8$.

So, we can write it as :

$2x^2 -8x-6+9x^2-8$

Writing like terms together:

$= 2x^2+9x^2-8x-6-8$

$=11x^2-8x-14$

Hence , the answer is $11x^2-8x-14$.
