Question 1: Computing Polynomials [35 marks A polynomial is a mathematical expression that can be built using constants and variables by means of addition, multiplication and exponentiation to a non-negative integer power. While there can be complex polynomials with multiple variable, in this exercise we limit out scope to polynomials with a single variable. The variable of a polynomial can be substituted by any values and the mapping that is associated with the...

A polynomial p(x) is an expression in variable x which is in the form axn + bxn-1 + …. + jx + k, where a, b, …, j, k are real numbers, and n is a non-negative integer. n is called the degree of polynomial. Every term in a polynomial consists of a coefficient and an exponent. For example, for the first term axn, a is the coefficient and n is the exponent. This assignment is about representing and computing...

Create a class to represent a term in an algebraic expression. As defined here, a term consists of an integer coefficient and a nonnegative integer exponent. E.g. in the term 4x2, the coefficient is 4 and the exponent 2 in -6x8, the coefficient is -6 and the exponent 8 Your class will have a constructor that creates a Term object with a coefficient and exponent passed as parameters, and accessor methods that return the coefficient and the exponent. Your class...
