Penjelasan dengan langkah-langkah:
gunakan rumus turunan
f(x) = u/v
f'(x) = (u'v - uv')/v²
dari soal
f(x) = (20x - 2)/(2x - 1)
u = 20x - 1
u' = 20
v = 2x - 1
v' = 2
f'(x) = [20(2x - 1) - (20x - 1)2]/(2x - 1)²
f'(x) = [(40x - 20) - (20x - 2)/(2x - 1)²
f'(x) = (40x - 20 - 20x + 2)/(2x - 1)²
f'(x) = (20x - 18)/(2x - 1)²
