Question

write the expression which represents polynomial​

Answer 1

In general, an expression with one or more than one term (with non- negative integral exponents of the variables) is called a 'Polynomial'. The sum (or difference) of two like terms is a like term with coefficient equal to the sum (or difference) of coefficients of the two like terms.
