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

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

The factors of x^3-x^2y-x y^2+y^3 are (a (x+y)(x^2-x y+y^2) (b) (x+y)(x^2+x y+y^2) (c) (x+y)^2(x-y) (d) (x-y)^2(x+y)

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

The factors of x^(3)-x^(2)y-xy^(2)+y^(3) are (a (x+y)(x^(2)-xy+y^(2))(b)(x+y)(x^(2)+xy+y^(2))(c)(x+y)^(2)(x-y)(d)(x-y)^(2)(x+y)

Divide : 36x^(2)y^(2) + 42 xy^(3) - 24 x^(3)y^(2) - 12 y^(5) by - 6y^(2)

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

Let (x,y) be a variable point on the curve 4x^(2)+9y^(2)-8x-36y+15=0 . Then min (x^(2)-2x+y^(2)-4y+5)+"max"(x^(2)-2x+y^(2)-4y+5) is- (A) 325/36 (B) 36/325 (C) 13/25 (D) 25/13
