If y=(x^2)*(x-10), work out dy/dx
The question is pretty straightforward and asks you to find the derivative of y, which is a function of x. The most simple way to do this is to first eliminate the brackets and then derive. Thus we get y=x^3-10x^2, so dy/dx= 3x^2-20x.

Can you explain induction and go through an example?
x^3 + 2x^2 - 9x - 18 = (x^2 - a^2)(x + b) where a,b are integers. Work out the three linear factors of x^3 + 2x^2 - 9x - 18. (Note: x^3 indicates x cubed and x^2 indicates x squared).
Plot the graph of 1/x for x greater than 0.
