The trinomial \left(x^2-4x+4\right) is a perfect square trinomial, because it's discriminant is equal to zero. Using the perfect square trinomial formula. Factoring the perfect square trinomial. We can solve the integral \int\frac{x-8}{x\left(x-2\right)^{2}}dx by applying integration by substitution method (also called U-Substitution). First, we must identify a section within the integral with a new variable (let's call it u), which when substituted makes the integral easier. We see that x-2 it's a good candidate for substitution. Let's define a variable u and assign it to the choosen part.
