Zounds!
Algebraic expressions are the written relations of or between variables. For example, x2, 1/x, and x + y + z are all algebraic expressions. Algebraic equations are simply algebraic expressions that equate to something. For example, x2 = 4, 1/x = y, and x + y + z = 42 are all algebraic equations. In general, one differentiates algebraic expressions from exponential, trigonometric, hyperbolic, and logarithmic expressions by requiring algebraic expressions to be confined to polynomial expressions. I've added a link regarding polynomials below.
If the expressions are w, x, y, z then to show that no two of them are equal is shown by(w-x)*(w-y)*(w-z)*(x-y)*(x-z)*(y-z) ≠0.Note that w .ne. x AND x .ne. y AND y .ne. z is not enough since it is possible for x = z.
No. There are no landforms that start with Z.
