Vertex form of equation is y = 4(x+ 0.5)^2+0

Explanation:

y = 4x^2 +4x+1 or y = 4(x^2 +x) +1

y = 4(x^2 +x + 0.5^2) -1+1; [4*0.5^2=1] or

y = 4(x+ 0.5)^2+0 . Comparing with vertex form of equation

y = a(x- h)^2+k ; (h,k) being vertex, we find

h=-0.5 and k= 0 . So vertex is at (-0.5,0) and

vertex form of equation is y = 4(x+ 0.5)^2+0 [Ans]
