If `xy = ae ^(x) + be^(-x)` then `xy _(2) + 2y _(1) - xy =`

The differential equation by eliminating the arbitrary constant from the equation xy=ae^(x)+be^(-x)+x^(2) is xy_(2)+ky_(1)-xy=k then k=

(1) y = ae^(4x) -be^(-3x) +c (2) xy = ae^(5x) +be^(-5x)

If xy = ae^(x) + be^(-x) satisfies the equation Axy'' +By' = xy , then |A-B| is__________.

If xy = ae^(x) + be^(-x) satisfies the equation Axy'' +By' = xy , then |A-B| is__________.

The differential equation of the curve xy=ae^(x)+be^(-x)+x^(2) is xy_(2)+ay_(1)+bxy+x^(2)-2=0 .then the value

If xy != 0 and sqrt((xy)/(3)) = x , what is y? (1) x/y = 1/3 (2) x = 3

Add the following expressions using horizontal method : -x^(2)y + xy^(2) + 2xy , 3x^(2) y + 4xy^(2) + 5xy and 7x^(2)y - 10xy^(2) - xy

If x:y::5:2, then (x ^(2) - xy + y ^(2))/( x ^(2) + xy + y ^(2)) = ?

If xy = 6 and x ^(2) y + xy ^(2) + x + y = 63, then the value of x ^(2) + y ^(2) is
