$"The vertex form is : "y=1/2(x+3/2)^2-41/8$

$"The vertex form is formed as y="a(x-h)^2+k$

$"Where (h,k) is vertex coordinates"$

$"we should rearrange the given equation."$

$y=1/2x^2+3/2x-4$

$y=1/2x^2+3/2xcolor(red)(+9/8-9/8)-4$

$y=1/2(color(green)(x^2+3x+9/4))-9/8-4$

$color(green)(x^2+3x+9/4)=(x+3/2)^2$

$y=1/2(x+3/2)^2-41/8$

What is the vertex form of y= 1/2x^2 + 3/2x -4y= 1/2x^2 + 3/2x -4?
