The equality 1/4 sum(zi, zi) = 3(xi + 2)^2 is incorrect; it should be 1/4 sum(zi, zi) = 1/4 * 3(xi + 2)^2

Hi,
Which tutorial are you refering to please?
It’s this one.
I think, @chrobles misunderstood.
There is no equality here. i.e., these are two assignment statements separated by a comma.
o = 1/4 sum(z_i)
z_i = 3(x_i + 2)^2
Thanks for clarifying @InnovArul, that’s correct! My mistake.
