if A=(2,10) and C=(8,4). Find point B if it lies on the X-axis and AB+BC is a minimum.

Let B=(x,0). Use Pythagoras to find the the distance between A and B as a function of x, and to find the distance between C and B as a function of x. Add the two distances - the sum will be a function of x. Differentiate the result with respect to x and set the result to zero. Solve for x.
