Hello there,
This is a quadratic equation, so if you graph any quadratic equation with real solutions, you will see that there are two x-intercepts. Therefore, you need to show both x-intercepts.
For x^2 - 4x + 4 = 0, solve for x and you will have the two x-intercepts.
I assume you know how to solve for x so I will leave this problem as such. However, if you require more help, please write back!
