x + y = 7 => x = 7 - y thay vào x.y ta có:

           ( 7 -y) y = 10 =>7y - y^2 = 10 => y^2 - 7y + 10 = 0 => y^2 -2y - 5y +10 => y( y-2) - 5 (y - 2) = 0

 => ( y - 5)(y - 2)  = 0 => y = 5 hoặc 2  => x = 2 hoặc 5 ( Nếu bạn thêm đk  x > y hay y>x chior có một trường hợp thôi)

(+) y = 5 và x = 2 

=> x - y = 2- 5 = -5

x^2 + y^2 = 2^2 + 5^2 = 4 + 25 = 29 

x^3 + y^3 = 2^3 + 5^3 = 8 + 125 = 133 

x^3 - y^3 = 2^3 - 5^3 = 8 -125 = -117 

(+) Tương tự x = 5 và y = 2
