Question

Simplify: 5x²-7xy+y²+3y²-2x²+4xy-x²+2y² ​

Answer 1

B = 6x²–8xy–y² + 2xy–2y²–x². => B = 5x² - 3y²- 6xy. A = x²–5xy+2y² + y²–2xy–3x². => A = -2x² –7xy+3y². S = B - A. => S = 5x² - 3y²- 6xy ...

Answer 2

Step-by-step explanation:

5x^2 -7xy +y^2 +3y^2 - 2x^2 + 4xy - x^2 + 2y^2

5x^2-2x^2-x^2-7xy+4xy+3y^2+y^2+2y^2

2x^2-3xy+6y^2
