Question 1

Add [tex]\left(7x^6 + 10x^2 - 10\right) + \left(3x^6 - 6x^3 + 4\right)[/tex].

A. [tex]10x^6 + 4x^2 - 6[/tex]

B. [tex]10x^6 + 4x^3 - 6[/tex]

C. [tex]10x^6 - 6x^3 + 10x^2 - 6[/tex]

Answer :

Let's add the two polynomials step-by-step:

We start with the expression:
[tex]\[
(7x^6 + 10x^2 - 10) + (3x^6 - 6x^3 + 4)
\][/tex]

1. Combine like terms. We'll add the coefficients of terms with the same degree:

- [tex]\(x^6\)[/tex] terms: [tex]\(7x^6 + 3x^6 = 10x^6\)[/tex]
- [tex]\(x^3\)[/tex] terms: There is no [tex]\(x^3\)[/tex] term in the first polynomial, so we only have [tex]\(-6x^3\)[/tex].
- [tex]\(x^2\)[/tex] terms: [tex]\(10x^2\)[/tex] is the only [tex]\(x^2\)[/tex] term present.
- Constant terms: [tex]\(-10 + 4 = -6\)[/tex]

2. Write the complete expression:

[tex]\[
10x^6 - 6x^3 + 10x^2 - 6
\][/tex]

This gives us the final result: [tex]\(10x^6 - 6x^3 + 10x^2 - 6\)[/tex].

So, the correct choice is [tex]\( \boxed{10x^6 - 6x^3 + 10x^2 - 6} \)[/tex].
