$\int\frac{1}{10^{-262}+2\cdot 10^{-131}x+x^{2}}dx$
Learn how to solve integrals of rational functions problems step by step online. Find the integral int(1/((10^(-131)+x)^2))dx. Expand the expression \left(10^{-131}+x\right)^2 using the square of a binomial: (a+b)^2=a^2+2ab+b^2. Solve the integral by applying the formula \displaystyle\int\frac{x'}{x^2+a^2}dx=\frac{1}{a}\arctan\left(\frac{x}{a}\right). Multiply the fraction by the term . As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration C.
