f(x)=2(2x+1)(x-1) carilah turunannya f'(x)=..? dan f'(2)=..? mohon bantuannya

difoto ya.. semoga membantu..

Fungsi turunan

f(x) = 2(2x+1)(x-1)
f(x)= (4x+2)(x-1)
f(x)= u(x). (v(x)

u = 4x +2 --> u' = 4
v = x-1 --> v' = 1
f' (x)= u'v + uv'

f' (x)= 4(x-1) + (4x+2)(1)

f '(2) = 4(2-1) + (4.2 + 2)(1)
f '(2) = 4(1) + 10(1)
f '(2)= 14
