Question

Define symmetric function of the root with one example

Answer 1

If the function using the roots of the quadratic f(x1,x2) doesn't change on interchanging x1 and x2, then the function, f, is symmetric. In other words, an expression in x1 and x2, which remains the same when x1 and x2 are interchanged, is called a symmetric function in x1 and x2.we
