Evaluate :
`( sqrt(2)x + sqrt(3)y ) ( sqrt(2)x + sqrt(3)y )`

sqrt(2)x + sqrt(3)y=0 sqrt(5)x - sqrt(2)y=0

sqrt(2)x+sqrt(3)y=0 sqrt(3)x+sqrt(8)y=0

sqrt (2x) -sqrt (3y) = 0sqrt (3x) -sqrt (3y) = 0

sqrt(2)x+sqrt(3)y=0sqrt(3)x-sqrt(8)y=0

Solve the following system of linear equations (with rational denominator) by using the method of elimination : sqrt(3)x - sqrt(2)y = sqrt (3) and sqrt(5)x + sqrt(3)y = sqrt(2) .

Evaluate (sqrt(x)+sqrt(y))(sqrt(x)-sqrt(y))
