Flashcard 4 - Math Reasoning Flashcard Set for the GED Test

The methods for solving, also known as finding the roots or zeroes of a quadratic polynomial are: by factoring, by completing the squares, and by using the quadratic formula.

The quadratic formula: \begin{array}{*{20}c} {x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}} & {{\rm{when}}} & {ax^2 + bx + c = 0} \ \end{array} can be used to solve every quadratic polynomial.
