`9(x -2y)^(2) + 36 (x -2y) (x + y) + 36 (x + y)^(2)`

16(x+y)^(2)-36(x-y)^(2)=

24x ^(3) - 36x ^(2)y

Factorise: 25(x+y)^(2)- 36 (x-2y)^(2).

5x + 2y = 31 3x + 7y = 36

(9x^(2)-25y^(2)+60y-36)/((3x+5y-6))

Image of ellipse 4x^2 + 9y^2 = 36 in the line y=x is : (A) 9x^2 + 4y^2 = 36 (B) 3x^2 + 2y^2 = 36 (C) 2x^2+3y^2 = 36 (D) none of these
