2) We used the inner product in a Hilbert space to define its norm. That leaves open the question of whether two different inner products could lead to the same norm. Show that that is not the case, by doing the following. (a) For a real Hilbert space, show that (x, y) ||r + y||? – ||x – y|| (b) For a complex Hilbert space, show that (x, y) = 1 ||a + y||? + i||x + iy||? – ||x – y||? – i||x – iy|?|. -

Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
