A spur gearset has a module of 6 mm and a velocity ratio of 4. The small pinion has 16 teeth. Find the number of teeth on the large driven gear, the pitch diameters, and the theoretical center-to-center distance.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
