Problems Using Wolfram Alpha

Question

I've always had some problem with the usage of wolfram alpha.It computes simple derivates, integrals and solves simple linear and quadratic equations flawlessly.It seems to me that it ignores step by step solution for harder problems.It only outputs the answer and the graph.I even searched this site for some clues, but couldn't make any sense out of these.

Currently I'm trying to solve and plot the following functions.

a) $$y = x^2 − 2x − 1$$ b) $$y =3x^2 +6x +2$$

c) $$y =1+ |x +2|$$ d)$$y = \frac{2}{(x-1)^2}$$

Any recommendations on how to efficiently input these expressions to get step by step solutions?

Answer 1

a) x^2-2x+1

b) 3x^2+6x+2

c) 1+Abs[x+2]

d) 2/(x-1)^2

Directly inputting these into Wolfram Alpha should turn something up. I linked up the first example so you can see what it looks like when entered.
