Answer 2

Answer:

2(3x + 5y) (x + 2y)

Step-by-step explanation:

Factorize :  (x - y)² - 7 (x² - y²) + 12 (x + y)²

=========

• (x - y)² - 7 (x² - y²) + 12 (x + y)²=
• x²+ y²- 2xy - 7x² + 7y² + 12 (x²+2xy+y²)=
• 12x²+24xy+12y²-6x²+8y²-2xy=
• 6x²+20y²+22xy=
• 2(3x²+10y²+11xy)=
• 2(3x²+6xy+10y²+5xy)=
• 2(3x(x+2y)+5y(2y+x))=
• 2(3x + 5y) (x + 2y)
