`int(x+1)(x+2)^7(x+3)dx` is equal toA. `((x+2)^(10))/(10)-((x+2)^(8))+C`B. `((x+1)^(2))/(2)-((x+2)^(8))/(8)-((x+3)^(2))/(2)+C`C. `((x+2)^(10))/(10)+C`D. `((x+1)^(2))/(2)+((x+2)^(8))/(8)+((x+3)^(2))/(2)+C` |
Answer» Correct Answer - A (a) `(x+1)(x+3)=(x+2-1)(x+2-1)` `=(x+1)^(2)-1` `therefore int(x+1)(x+2)^(7)(x+3)dx=int{(x+2)^(9)-(x+2)^(7)}dx=((x+2)^(10))/(10)-((x+2)^(8))/(8)+C` |
