Write each equation in vertex form.
y=1/2x2 + x
(the x2 is in the middle of the fraction)

I presume you mean y= (1/2)x^2+ x since otherwise it wouldn't be quadratic!
I would first write that as y= (1/2)(x^2+ 2x). Now "complete the square". Do you know how to do that?
No they are not in () we have to write it in vertex form
