8 becomes 800 the 7 becomes 70 and 5 is just 5. Now x it by the 4
800x4=3200
70x4=. 280
5x4=. 20
-------
3500

3|x + y|² - (xy)²
x = 3
y = -5
<u>Step 2: Evaluate</u>
- Substitute: 3|3 - 5|² - (3(-5))²
- Multiply: 3|-2|² - (-15)²
- Exponents: 3|-2|² - 225
- Absolute Value: 3(2)² - 225
- Exponents: 3(4) - 225
- Multiply: 12 - 225
- Subtract: -213
