Vedclass · Answer

(D) To solve the integral $\int {\frac{{a{x^{ - 2}} + b{x^{ - 1}} + c}}{{{x^{ - 3}}}}} \,dx$,first simplify the integrand by dividing each term in the numerator by ${x^{ - 3}}$: $\frac{{a{x^{ - 2}} + b{x^{ - 1}} + c}}{{{x^{ - 3}}}} = a{x^{ - 2 - ( - 3)}} + b{x^{ - 1 - ( - 3)}} + c{x^{ - ( - 3)}} = a{x^1} + b{x^2} + c{x^3}$. Now,integrate the expression with respect to $x$: $\int {(ax + b{x^2} + c{x^3})} \,dx = a\int x \,dx + b\int {{x^2}} \,dx + c\int {{x^3}} \,dx$. Using the power rule $\int {{x^n}} \,dx = \frac{{{x^{n + 1}}}}{{n + 1}} + k$,we get: $a(\frac{{{x^2}}}{2}) + b(\frac{{{x^3}}}{3}) + c(\frac{{{x^4}}}{4}) + k = \frac{1}{2}a{x^2} + \frac{1}{3}b{x^3} + \frac{1}{4}c{x^4} + k$. Thus,the correct option is $D$.

$\int {\frac{{a{x^{ - 2}} + b{x^{ - 1}} + c}}{{{x^{ - 3}}}}} \,dx = $
