$\int\limits_{}^{}8.1x ^{2} + 8.4x - 7dx$

2. satellite73

$\int x^ndx=\frac{x^{n+1}}{n+1}$

3. lilg132

${8.1\over 3} x ^{3} + {8.4x ^{2} \over 2} - 7x$

??

looks right to me although remember to add +c you are dealing with an indefinite integral

6. lilg132

yes i forgot the plus c in the end but are you sure that is correct ? :D

7. Australopithecus

100%

8. lilg132

you can also simplify it but you can usually use wolfram alpha to check your answers although be careful their answers wont always match yours when you are integrating as it might use a different method than you
