Solving a problem with term 'decomposition'.
The equation is not making any sense to me - nothing is comparable to the other. Consider the decomposition of the equation 19x^2 + 23x +10 6x^3 + 17x^2 - 4x â?" 3 into partial A + B + C X+3 2x-1 3x-1. How does this work????? I have 4 solutions, but I don't know how to make them work.

Distance between two runners at a specific point in time.
Tony and Maria are training for a race by running all the way up and down a 700m long ski slope. They each run up the slope at different constant speeds. Coming down the slope, each runs at double his or her uphill speed. Maria reaches the top first, and immediately starts running back down, meeting Tony 70m from the top. When M
