Given y=2x(x^2-1)^5, show that dy/dx = g(x)(x^2-1)^4 where g(x) is a function to be determined.

y=2x(x 2 -1) 5 --> y=uv, where u=2x; v=(x 2 -1) 5 --> thus product rule required.u'=2v'=10x(x 2 -1) 4 Product rule: dy/dx = uv' + v'uTherefore: dy/dx = 2x(10x(x 2 -1) 4 ) + 2(x 2 -1) 5 g(x) = (22x 2 -2)
