Express the function y = 2x^ 2 + 8x + 1 in vertex form.

ax^2+bx+c , to find the values of a, b, and c.
   
a=2,b=â’8,c=1
   
Convert to vortex form of parabola a(x+d)^2+e
   
Find the value of d:
   
d= -8:(2*2)
   
d= -(4/2)
   
d= -2
       
solve for e:
   
e= 1-(64/8) or

e= 1-8
   
e= -7 2(x-2)^2-7
   
Then balance both sides of the equation y=2(xâ’2)^2â’7
