$9\int_{-1}^{1} xdx$
Learn how to solve special products problems step by step online. Integrate the function 9x from -1 to 1. The integral of a constant times a function is equal to the constant multiplied by the integral of the function. 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. Simplify the expression inside the integral.
