$\int\left(3x^2-x-x-2\right)dx$
Learn how to solve calcul intégral problems step by step online. Integrate int(3x^2-x-(x+2))dx. Apply the formula: x\left(a+b\right)=xa+xb, where a=x, b=2, x=-1 and a+b=x+2. Simplify the expression. The integral \int3x^2dx results in: x^{3}. The integral \int-2xdx results in: -x^2.
