How do you find the definite integral of #(x^4 - 1)/( x^2 + 1) dx# from -5 to -2? Calculus Introduction to Integration Definite and indefinite integrals 1 Answer Alberto P. Nov 3, 2016 36 Explanation: #int_-5^-2(x^4-1)/(x^2+1)dx=int_-5^-2(x^2-1)dx=# #[x^3/3-x]_-5^-2=-8/3+2-(-125/3+5)=(-8+6+125-15)/3=108/3=36# Answer link Related questions What is the difference between definite and indefinite integrals?
