₀^ 4 ^2 x (1+ x)(2+ x) d x=
Options
- A( 3 4 )
- B1 3 ( 4 3 )
- C( 4 3 )
- D1 4 ( 3 4 )
Correct answer
C. ( 4 3 )
Step-by-step solution
Put 1+ x= t ^2 x ~d x= dt When x=0, t =1 and when x= 4 , t =2 aligned & ₀^ / 4 ^2 x (1+ x)(2+ x) d x & = ₁^2 dt t (1+ t ) & = ₁^2 dt t - ₁^2 dt 1+ t & = [ t - _ (1+ t (1) ]₁^2 & = _ e 2- _ e 3+ _ e 2 & = _ e ( 4 3 ) aligned
