Choose the correct sum of the polynomials (2x3 − 5x − 1) + (4x3 + 8x + 3).
a2x3 − 3x − 4
b6x3 + 3x + 2
c2x3 + 3x + 2
d6x3 − 3x − 2

Option (b) is correct.

Step-by-step explanation:

Given: Polynomial and

We have to find the sum of given polynomial and choose the correct option from given options.

Consider the given Polynomial and

We have to find the sum that is

Apply plus minus rule

We have,

Now adding like terms, we have,

Like terms are terms having same variable with same degree.

Simplify , we have,

Thus, option (b) is correct.

i can

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
