See explanation...
Explanation:
A polynomial in a variable
So some examples of typical polynomials might be:
x2+3x−4
3x3−52x2+7
A polynomial function is a function wholse values are defined by a polynomial. For example:
f(x)=x2+3x−4
g(x)=3x3−52x2+7
A zero of a polynomial
For example,
A rational zero is a zero that is also a rational number, that is, it is expressible in the form
For example:
h(x)=2x2+x−1
has two rational zeros,
Note that any integer is a rational number since it can be expressed as a fraction with denominator
