------------------------------------------------ Simplify:

[tex]\left(3x^5 + 17x^3 - 1\right) + \left(-2x^5 - 6\right)[/tex]

A. [tex]x^5 + 17x^3 - 7[/tex]

B. [tex]x^5 - 11x^3 - 1[/tex]

C. [tex]5x^5 + 17x^3 + 7[/tex]

D. [tex]-6x^5 + 17x^3 + 6[/tex]

Answer :

Let's simplify the given expression step-by-step:

The expression given is:
[tex]\[
(3x^5 + 17x^3 - 1) + (-2x^5 - 6)
\][/tex]

1. Combine Like Terms:

- Combine the terms with [tex]\(x^5\)[/tex]:
- [tex]\(3x^5 + (-2x^5) = (3 - 2)x^5 = 1x^5\)[/tex]

- The term with [tex]\(x^3\)[/tex] is [tex]\(17x^3\)[/tex], and it doesn't have any like terms to combine with.

- Combine the constant terms:
- Consists of [tex]\(-1\)[/tex] and [tex]\(-6\)[/tex]: [tex]\(-1 + (-6) = -7\)[/tex]

2. Write the simplified expression:

Put all the simplified terms together:
[tex]\[
x^5 + 17x^3 - 7
\][/tex]

Thus, the simplified expression is [tex]\(x^5 + 17x^3 - 7\)[/tex]. Therefore, the correct choice is:

A. [tex]\(x^5 + 17x^3 - 7\)[/tex]
