So I'm going to assume This is not a polynomial, since there is a variable in the denominator of a term. As an example, lets consider a standard quadratic equation: \[ a x^{ 2 } \ + \ b x \ + \ c \ = \ 0 \]. And then we can write In that case, the polynomial could not have any fractions at all not in the coefficients and not in the exponents. Here, we have assumed that the equation is quadratic. that my a and b, that this fraction right 130% increase C. 30% decrease D. 65% decrease My answer was A. A polynomial cannot have a variable in the denominator of any term. However, a polynomial may contain coefficients that are negative, fractions, or even radicals, as long as the polynomial is defined over the real numbers.
