Completing the Square - Germanna Community College
www.germanna.edu“Completing the square” is another method of solving quadratic equations. It allows trinomials to be factored into two identical factors. Example: 2 + 4 + 4 ( + 2)( + 2) or ( + 2)2 To complete the square, it is necessary to find the constant term, or the last number that will enable factoring of the trinomial into two identical factors.
