To tackle the integral \( \int x^{4} e^{2x^{2} + x} \, dx \), you'll want to consider using integration by parts or substitution techniques, given the polynomial multiplied by the exponential function. Specifically, you can let \( u = 2x^{2} + x \), then differentiate to find \( du \) and express \( dx \) accordingly. This transforms the expression and simplifies the integration process. Remember, applying integration techniques thoughtfully is key! Next, always be cautious about missing constants and terms during substitution, as it can lead to incorrect final results. A common mistake is not accounting for the differential correctly when switching variables. When performing integration by parts, keep track of which parts are being differentiated and integrated, and don't forget to apply the limits if you turn your indefinite integral into a definite one later on! Happy integrating!
