What are the most difficult things about learning a foreign language? What is the best way to overcome them?

Solve: sqrt(3 - x) = sqrt(2 + x) + 1
Squaring both sides, (3-x)= (2+x)+1 + 2(sqrt(2+x)) Squaring again and solving, x^2 - x -2 =0 x(x-1) = 2 Hence, x=2 and x= -1

What is polymorphism?
Polymorphism is the ability of an object to take on multiple forms. Most commonly polymorphism is used in Object Oriented Programming(OOP) when a parent class reference is used to refer to a child class object.
