1. y=(x-4)(x+2)

2. y=2x^2-4x+1

The midpoint of the x-intercepts of a parabola has the same x value as the vertex.

the x-intercepts are obviously x=4 and x=-2

so the x value of the vertex is......

sub that back into the equation to get the y value.

for the second one, just use the method of completing the square.
