    Exclamation Cubic and Quartic Functions Problems: Part 2

    I am having trouble with a couple of questions in terms of the proccess of solving the questions:

    3a Solve the equation x^4-2x^2+1=0 for x, where x is real
    3b(i)Find the x=axis intercepts
    3B(II)Find the minimum value
    (iii) Sketch the graph of y=P(X)

    I will be greatly apprecieated if any of you would have the time to help and explain these questions for me.
