$\int\frac{x^4+6x^2-7}{x^4+8x^2-9}dx$
Learn how to solve integral calculus problems step by step online. Integrate the function (x^4+6x^2+-7)/(x^4+8x^2+-9). Find the integral. Rewrite the expression \frac{x^4+6x^2-7}{x^4+8x^2-9} inside the integral in factored form. We can factor the polynomial x^4+6x^2-7 using the rational root theorem, which guarantees that for a polynomial of the form a_nx^n+a_{n-1}x^{n-1}+\dots+a_0 there is a rational root of the form \pm\frac{p}{q}, where p belongs to the divisors of the constant term a_0, and q belongs to the divisors of the leading coefficient a_n. List all divisors p of the constant term a_0, which equals -7. Next, list all divisors of the leading coefficient a_n, which equals 1.
