Roots of polynomials Cheat Sheet This chapter is concerned with identifying the relationship between the roots of quadratic, cubic and quartic polynomials.

We explain what the roots (or zeros) of a polynomial are and how to find them. With practice problems on finding polynomial roots.

2 days ago · A root of a polynomial P (z) is a number z_i such that P (z_i)=0. The fundamental theorem of algebra states that a polynomial P (z) of degree n has n roots, some of which may be degenerate.

A root (or zero) is where the polynomial is equal to zero: Put simply: a root is the x-value where the y-value equals zero.
