Question

Plz hurry and help! I'm in a hurry!

Answer 1

Answer:

$= -(9 + 9 \sqrt{3i} - (2 + \sqrt{3i} ) )\\ = -(9 - 2) + -(9 \sqrt{3 } - \sqrt{3} )i \\ = -7 + -(9 - 1) \sqrt{3} i \\ = -7 -8 \sqrt{3} i$

Answer 2

Answer:

• -7 - 8√3i

Step-by-step explanation:

Given

• z₁ = 9 + 9√3i
• z₂ = 2 + √3i

To find

• z₂ - z₁

Solution

• z₂ - z₁  =
• 2 + √3i - (9 + 9√3i) =
• 2 - 9 + √3i - 9√3i =
• -7 + (1 - 9)√3i =
• -7 - 8√3i

Second option is correct (you have selected it right)
