Answer:
See below ~
Step-by-step explanation:
<u>Q1</u>
- y = (x + 3i)(x - 7)
- y = x² + 3ix - 7x - 21
- <u>y = x² + (3i - 7)x - 21</u>
<u>Q2</u>
- y = (x - √5)(x - i)
- y = x² - √5x - ix + √5i
- <u>y = x² - (√5 + i)x + √5i</u>
Answer:
y = 1

Step-by-step explanation:
<u>Step 1: Define</u>
y = 1/7(x + 5)
x = 2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: y = 1/7(2 + 5)
- (Parenthesis) Add: y = 1/7(7)
- Multiply: y = 1
