Let's compute the integral: <math><mo>∫(</mo><msup><mrow><mi>x</mi></mrow><mrow><mn>2</mn></mrow></msup><mo> + </mo><mn>1</mn><mo>)dx</mo></math>
 <math><mo>∫(</mo><msup><mrow><mi>x</mi></mrow><mrow><mn>2</mn></mrow></msup><mo>)dx</mo><mo> + </mo><mo>∫(</mo><mn>1</mn><mo>)dx</mo></math>
 <math><mfrac><mrow><msup><mrow><mi>x</mi></mrow><mrow><mn>3</mn></mrow></msup></mrow><mrow><mn>3</mn></mrow></mfrac><mo> + </mo><mi>x</mi></math>
Indefinite integrals are defined up to an additive constant <m>C</m>, so this yields: <math><mfrac><mrow><msup><mrow><mi>x</mi></mrow><mrow><mn>3</mn></mrow></msup></mrow><mrow><mn>3</mn></mrow></mfrac><mo> + </mo><mi>x</mi><mo> + </mo><mi>C</mi></math>
