This problem addresses some common algebraic errors. for the equalities stated below assume that x and y stand for real numbers. assume that any denominators are non-zero. mark the equalities with t (true) if they are true for all values of x and y, and f (false) otherwise.(x+y)^2 = x^2 + y^2.(x+y)^2 = x^2 + 2xy+y^2.x/ (x+y)= 1/y. x-(x+y) = y. sqrt{x^2} = x. sqrt{x^2} = |x|.sqrt{x^2+4} = x+2.1(x+y) = 1/x + 1/y.
