Answer:

The answer to your question is  -12 - 10i    

Step-by-step explanation:

Subtract (3 + 2i) from (-9 - 8i)

Process

To subtract these numbers just subtract the real numbers and subtract the imaginary numbers.

   (-9 - 8i) - (3 + 2i)

Simplifying

= (-9 - 3) + (-8i - 2i)

Result

= -12 - 10i

Find the sum and choose the correct answer. <br> 2n 3 + 4n 2 - 7 and -n 3 + 8n - 2
MrRa [10]

The sum of the polynomials 2n³ + 4n² - 7 and -n³ + 8n - 2 will be n³ + 4n² + 8n - 9. Then the correct option is B.

<h3>What is polynomial?</h3>

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The polynomials are given below.

2n³ + 4n² - 7 and -n³ - 8n - 2

The sum of the polynomials will be

⇒ 2n³ + 4n² - 7 + (-n³ - 8n - 2)

⇒ 2n³ + 4n² - 7 - n³ - 8n - 2

⇒ n³ + 4n² - 8n - 9

The sum of the polynomials 2n³ + 4n² - 7 and -n³ + 8n - 2 will be n³ + 4n² - 8n - 9.

Then the correct option is B.
