Tolong lah saya please saya doakan masuk surga

misal

$u = (4x + 2) \ du = 4 : dx \ frac{du}{4} = dx$

maka

$int {(4x + 2)}^{ - 2} dx \ = int {u}^{ - 2} frac{du}{4} \ = frac{1}{4} int {u}^{ - 2} du \ = frac{1}{4} ( frac{1}{ - 2 + 1} {u}^{ - 2 + 1}) + c \ = frac{1}{4} ( - {u}^{ - 1} ) + c \ = - frac{1}{4} (4x + 2)^{ - 1} + c$
