Solve the quadratic equation by completing the square.
0 = x2 – 6x + 4
–4 = x2 – 6x
–4 + 9 = (x2 – 6x + 9)
5 = (x – 3)2
What are the two solutions of the equation?
x = StartRoot 5 EndRoot and x = negative StartRoot 5 EndRoot
x = 3 + StartRoot 5 EndRoot and x = 3 – StartRoot 5 EndRoot
x = 5 + StartRoot 3 EndRoot and x = 5 – StartRoot 3 EndRoot
x = StartRoot five-thirds EndRoot and x = negative StartRoot five-thirds EndRoot
