Kayla begins with a quadratic equation in vertex/graphing form. She is solving the equation for x. Step 1: y=a(x−h)2+k

Step 2: ya=(x−h)2+k

Step 3: ya−k=(x−h)2

Step 4: ±ya−k−−−−−√=x−h

Step 5: h±ya−k−−−−−√=x

Kayla is certain she has made a mistake but isn’t sure where. Identify where she made her mistake. Solve the equation showing all work.
