(3-x) 4-x d x= (Where C is a constant of integration.)
Options
- A2 3 (4-x)^ 3 / 2 + 2 5 (4-x)^ 5 / 2 +C
- B- 2 5 (4-x)^ 5 / 2 + 2 3 (4-x)^ 3 / 2 +C
- C2 3 (4-x)^ 3 / 2 - 2 5 (4-x)^ 5 / 2 +C
- D2 5 (4-x)^ 5 / 2 - 2 5 (4-x)^ 3 / 2 +C
Correct answer
C. 2 3 (4-x)^ 3 / 2 - 2 5 (4-x)^ 5 / 2 +C
Step-by-step solution
aligned & (3-x) 4-x d x & = (4-x)-1 4-x d x= (4-x)^ 3 2 -(4-x)^ 1 2 d x & = 2 5 (4-x)^ 5 / 2 + 2 3 (4-x)^ 3 / 2 +C & = 2 3 (4-x)^ 3 / 2 - 2 5 (4-x)^ 5 / 2 +C aligned
