8. ### How to graph a function by transforming a graph of a function form?

They want you to start up with graph of y=x^2 and get y=(x-3)^2, which is just shifted in x axis.
9. ### Solving an equation

I will consider like this (x^2 + ax+b)^2=x^4+2ax^3+(a^2+2b)x^2+2abx+b^2 Now you have three quadratic parts. Instead of expanding and simplifying each one of them you can directly write the final expression as...
