Question

How do I find zeros and roots for polynomial equations

Answer 1

The zeros and roots of polynomial expressions are the same. They are found by making the equation zero. For example for a polynomial:

`P(x)=a_nx^n+\cdots+a_2x^2+a_1x+a_0`

To find the roots (or zeros) we have to equal the polynomial to zero:

`\begin{gathered} P(x)=0 \\ a_nx^n+\cdots+a_2x^2+a_1x+a_0=0 \end{gathered}`

And the solutions - in other words the values of x that make the polynomial zero - are the roots (or zeros).
