Viet cac bt sau duoi dang tong 2 binh phuong:
1. 2x^2 + y^2 - 2xy + 10x + 25
2. x^2 - 2x + y^2 + 6y + 10
-Anonymous
1. 2x^2 + y^2 - 2xy + 10x + 25
2. x^2 - 2x + y^2 + 6y + 10
1) 2x² + y² - 2xy + 10x + 25 = (x² + 10x + 25) + (x² - 2xy + y²) = (x+5)² + (x-y)²
2) x² - 2x + y² + 6y + 10 = ( x² - 2x + 1) + (y² + 6y + 9) = (x-1)² + (y+3)²
-Anonymous
2) x² - 2x + y² + 6y + 10 = ( x² - 2x + 1) + (y² + 6y + 9) = (x-1)² + (y+3)²
