Write the following in the expanded form: (ab+bc+ca)^(2) (ii) ((x)/(y)+(y)/(z)+(z)/(x))^(2)

Area of the triangle formed by (x_(1),y_(1)),(x_(2),y_(2)),(3x_(2)-2x_(1),3y_(2)-2y_(1)) (in sq.units) is

Solve for x and y : 2^(y-x) (x + y) = 1 and (x + y)^(x - y) = 2 .

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))

Simplify : ( 3y ( x - y) - 2x ( y -2x))/( 7x ( x - y) - 3 ( x ^(2) - y ^(2)))
