Vertex form of equation is # y= (x-6)^2-4#

#y=(x-4)(x-8) or y= x^2-12 x +32# or

# y= (x^2-12 x +36)-36+32# or

# y= (x-6)^2-4# Comparing with vertex form of

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

here #h=6 , k= -4 #, so vertex is at #(6,-4)# and vertex form of

equation is # y= (x-6)^2-4#
