A boat is travelling at a velocity represented by 2x^3 - 10x^2 + 7. At the same time, current is pushing the boat in the same direction with a velocity given by 5x^3 + 19x^2 + 4x. What is the total travelling velocity of the boat?

Question

A boat is travelling at a velocity represented by 2x^3 - 10x^2 + 7.  At the same time, current is pushing the boat in the same direction with a velocity given by 5x^3 + 19x^2 + 4x.  What is the total travelling velocity of the boat?

anonymous · Answer

subtract one polynomial from the other. If you get a negative value, the velocity is in the opposite direction that the first one.
