Solution

The image you uploaded contains a mathematical expression. I'll extract the text and work through the problem for you.

Given Information:

The image contains the following equation:

x23x+2x3+4x2+x+4dx\int \frac{x^2 - 3x + 2}{x^3 + 4x^2 + x + 4} dx

The integral requires simplification and then solving. Let's proceed with solving this.

Solution:

  1. Simplification: First, we'll check if the numerator can be factored or simplified with the denominator.

    The numerator is x23x+2x^2 - 3x + 2, which factors as: (x1)(x2)(x - 1)(x - 2)

    The denominator is x3+4x2+x+4x^3 + 4x^2 + x + 4. Let's analyze this for any possible factorization. If we cannot factor easily, we'll consider polynomial long division or partial fractions.

  2. Division or Partial Fraction: If the numerator and denominator can't be factored nicely together, we would typically attempt polynomial division, or we may use partial fraction decomposition.

  3. Integration: After simplifying, we'll find the antiderivative using standard integration techniques, such as substitution or direct integration.

Let's move forward with the computation to find the integral. I'll walk you through the solution step-by-step.

Partial Fraction Decomposition

The integral can be decomposed using partial fractions if the denominator can be factorized.

However, the denominator does not factor easily into simple linear or quadratic factors, so we should instead apply polynomial division to simplify the expression before integration.

I'll go through the necessary steps to solve this now.
