Write the following quadratics in vertex form by completing the square and find the vertex Example 1 y = x 2 2x 4 Solution Using completing the square method, y = (x 2 2xSubtract y from both sides Subtract y from both sides x^ {2}2x1y=0 x 2 2 x 1 − y = 0 This equation is in standard form ax^ {2}bxc=0 Substitute 1 for a, 2 for b, and 1y for c in the quadratic formula, \frac {b±\sqrt {b^ {2}4ac}} {2a} This equation is x = b/2a = 4/4 = 1 y (1) = 4 vertex at (1 , 4) Edit or in vertex form y = 2 (x 1)^2 4 vertical shift down 4 units hope that helped acobdarfq and 8 more users found this answer helpful heart outlined
