Final answer to the problem
Step-by-step Solution
Learn how to solve integrals of polynomial functions problems step by step online. Find the integral int(3a)da. The integral of a function times a constant (3) is equal to the constant times 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. Multiply the fraction and term in 3\cdot \left(\frac{1}{2}\right)a^2. As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration C.
