How do you evaluate #int x^2 + x + 4dx# for [0, 2]? Calculus Introduction to Integration Definite and indefinite integrals 1 Answer Dharma R. Sep 21, 2015 #38/3# Explanation: #int_0^2x^2+x+4dx=int_0^2x^2dx+int_0^2xdx+int_0^24dx =[x^3/3]_0^2+[x^2/2]_0^2+4[x]_0^2=8/3+4/2+8-0=38/3# Answer link Related questions What is the difference between definite and indefinite integrals?
