turunan fungsi f(x) = 2x2+3/x2+2x tolong dibantu yaa aku mohon

paling baik lengkapi dulu dh tnda kurung, biar gk maen tbak²an banyak
jika gini
f(x) = (2x² + 3)/(x² + 2x)
u = 2x² + 3 → u' = 4x
v=x² + 2x → v' = 2x + 2
f'(x) = (u'v - v'u)/v²
= (4x(x² + 2x) - (2x + 2)(2x² + 3))/(x² + 2x)²
= (4x³ + 8x² - (4x² + 6x + 4x² + 6))/(x² + 2x)²
= (4x³ + 8x² - 4x² - 6x - 4x² - 6)/(x² + 2x)²
= (4x² - 6x - 6)/(x² + 2x)²
