Equation at the end of step 2 : 2x 2 - x - 4 = 0 Step 3 : Parabola, Finding the Vertex : 3.2 Solving x2-2x+4 = 0 by Completing The Square . The derivative is zero when 2x^ {4/3}−2=0, which implies x=±1. Solve by Factoring x^2-2x-24=0. In order to complete the square, the equation must first be in the form x^{2}+bx=c.
