x - log |x + 2| + c
x - 2log |x + 2| + c
x + 2log |x + 2| + c
MCQ
रिकाम्या जागा भरा
उत्तर
`intx/(x + 2)dx` = x - 2log |x + 2| + c
Explanation:
`intx/(x + 2)dx = int((x + 2) - 2)/(x + 2)dx`
= `int((x + 2)/(x + 2) - 2/(x + 2))`dx
= `int(1 - 2/(x + 2))dx`
= `int1 . dx - 2int1/(x + 2)dx`
= x - 2log |x + 2| + c
