" 12."(40)/(x+y)+(2)/(x-y)=5,(25)/(x+y)-(3)/(x-y)=1

7(x-2y)^(2)-25(x-2y)+12

7(x-2y)^2-25(x-2y)+12

Find the products: (3/x-5/y)(9/(x^2)+(25)/(y^2)+(15)/(x y))

If (x)/(4) + ( y)/(3) = (5)/(12) and (x)/(2) + y = 1 then find the value of (x + y ) .

Find the following products and verify the result for x=-1,y=-2:(3x-5y)(x+y)(2)(x^(2)y-1)(3-2x^(2)y)((1)/(3)x-(y^(2))/(5))((1)/(3)x+(y^(2))/(5))

(5x + 3y) (5x-3y) (25x ^ (2) + 9y ^ (2))

For hyperbola whose center is at (1,2) and the asymptotes are parallel to lines 2x+3y=0 and x+2y=1, the equation of the hyperbola passing through (2,4) is (2x+3y-5)(x+2y-8)=40(2x+3y-8)(x+2y-8)=40(2x+3y-8)(x+2y-5)=30 these
