$\int_{-1}^{2} xdx$

Learn how to solve definite integrals problems step by step online. Integrate the function x^2+x-x^2 from -1 to 2. Cancel like terms x^2 and -x^2. Applying the power rule for integration, \displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}, where n represents a number or constant function, in this case n=1. Evaluate the definite integral. Simplifying.
