Completing the Square
Previously, you have solved equations of the form u2 = d by taking the square root of each side. This method also works when one side of an equation is a perfect square trinomial and the other side is a constant. 3.3 CCore ore CConceptoncept Completing the Square Words To complete the square for the expression x2 + bx, add ( b— 2) 2.
