And you could have gotten here The coefficient here is 1. In the case where we are dividing f / g and g is not a factor of f, and the degree of g is less than the degree of f, there is polynomial remainder whose degree is strictly less than that of g. So, for example, when g is a linear function (degree 1), f / g can have a constant remainder (degree 0). These division worksheets will produce problems with mixed formats for the quotient, but keeping the divisor and dividend as whole numbers. Dividing Fractions. The polynomial we’re dividing by has degree one and so, in this case, we’ll stop when the remainder is degree zero, i.e. 176 Chapter 4 Polynomial Functions The Remainder Theorem tells you that synthetic division can be used to evaluate a polynomial function. x plus 2 times x plus 8.
