After this will be your maxima and minima, this one there is more things to remember, I summarise them here first

Stationary points —> dy/dx = 0, solve for the coordinates

Remember that dy/dx is gradient at a point, this sounds superficial but it’s important when doing the first derivative test to determine whether the stationary point is a minimum, a maximum or something called inflection.

Second derivative test is an alternative way, using an entirely different approach altogether.

All these will be seen in the next part of differentiation.

Checked already. Same answer as before. This will be the form which you will be taking for the answer. The last three lines are for simplification only and it's not a must to do them.

Let me try once more. If the answer is still the same, then the answer given in the book is probably too over-simplified.
