Question

Simplify.

(x2 - y2 - 3xy) + (7xy + 3x2)

Answer 1

4x^2-y^2+4xy

Explanation:

Just combine like terms and do not forget that your adding the set of parentheses together.

x^2+3x^2

-y^2

-3xy+7xy

Answer 2

(x² - y² - 3xy) + (7xy + 3x²) = 4x² - y² + 4xy

Step 1: Define

Identify

(x² - y² - 3xy) + (7xy + 3x²)

Step 2: Simplify

1. [Order of Operations] Combine like terms (x²): (x² - y² - 3xy) + (7xy + 3x²) = 4x² - y² - 3xy + 7xy
2. [Order of Operations] Combine like terms (xy): (x² - y² - 3xy) + (7xy + 3x²) = 4x² - y² + 4xy
