SSC Higher Mathematics Note 2nd Chapter Algebraic Expressions. We are familiar with various types of algebraic expression. When one or more numbers and symbols representing numbers are combined meaningfully by anyone sign or more than one +, –, ×, ÷ of power or rational sign, a new symbol representing numbers is created. It is called an algebraic expression or in brief expression.
In any discussion, a literal symbol representing a number may be a variable or a constant. If such a symbol denotes any unscheduled element of the number set consisting of more than one element we call the symbol a variable and the set is called the domains. If the symbol denotes a definite number, it is called a constant. In any discussion, a variable can take any value from its domain, but the value of a constant remains fixed all through

There is no hard and fast rule for factorizing polynomials. Often a factor can be found by suitable rearranging the terms. Sometimes assuming the expression as the polynomial of the variable, we determine one or more than one factors by the factor theorem and considering the cyclic and symmetric properties of the expression, we determine the remaining factors.
