Mean normalization and Feature scaling.

Currently, I am working on multivariable regression problem data set and I came across a problem that my dataset have so many features with different features scale value and so google suggest me use mean normalization and feature scaling techniques but I don't understand which one we have to use mean normalization or feature scaling and why we are using mean normalization and feature scaling techniques simultaneously.?? and from where below formula derived .x(i) = x(i) - mean(x) / std(x)See More
