Quadratic polynomial
= Quadratic polynomial
{title2=$ax^2+bx+c,\quad a\ne0$}
A quadratic polynomial in one variable over a <field> has <polynomial degree> two and the displayed form. Its <roots of a polynomial> satisfy a <quadratic equation>. The <polynomial> and its associated <polynomial function> are distinct objects: over a <finite field>, different <polynomials> can define the same <function>.
