Q. Evaluate 3e3+22x1x2dx \int_{3}^{e^{3}+2} \frac{2 x-1}{x-2} d x . Write your answer in simplest form with all logs condensed into a single logarithm (if necessary).
  1. Identify Integral Type: Identify the type of integral. We are dealing with an integral of a rational function, which suggests that we might need to use partial fraction decomposition. However, in this case, the numerator is a first-degree polynomial and the denominator is a first-degree polynomial as well, but not factorable. We can simplify the integral by dividing the numerator by the denominator.
  2. Perform Long Division: Perform long division for the integrand (2x1)/(x2)(2x-1)/(x-2). When we divide 2x2x by xx, we get 22. Multiplying 22 by (x2)(x-2) gives us 2x42x-4. Subtracting this from 2x12x-1 gives us a remainder of 33. So, the integral can be rewritten as: (2+3/(x2))dx\int(2 + 3/(x-2)) \, dx from 2x2x00 to 2x2x11.
  3. Split into Two Integrals: Split the integral into two separate integrals. (2+3x2)dx=2dx+3x2dx\int(2 + \frac{3}{x-2}) \, dx = \int 2 \, dx + \int \frac{3}{x-2} \, dx. We can now integrate each term separately.
  4. Integrate Constant Term: Integrate the first term 2dx\int 2 \, dx. The integral of a constant is just the constant times the variable, so: 2dx=2x\int 2 \, dx = 2x.
  5. Integrate Fraction Term: Integrate the second term 3x2dx\int \frac{3}{x-2} \, dx. The integral of 1xa\frac{1}{x-a} is lnxa\ln|x-a|, so: 3x2dx=3lnx2\int \frac{3}{x-2} \, dx = 3\ln|x-2|.
  6. Combine Integral Results: Combine the results of the two integrals.\newlineThe combined integral is:\newline2x+3lnx22x + 3\ln|x-2|.
  7. Evaluate Definite Integral: Evaluate the definite integral from x=3x=3 to x=e3+2x=e^{3}+2. We substitute the upper and lower limits into the antiderivative: (2(e3+2)+3lne3+22)(2(3)+3ln32)(2(e^{3}+2) + 3\ln|e^{3}+2-2|) - (2(3) + 3\ln|3-2|).
  8. Simplify Expression: Simplify the expression.\newline2(e3+2)+3ln(e3)63ln(1)2(e^{3}+2) + 3\ln(e^{3}) - 6 - 3\ln(1) simplifies to:\newline2e3+4+3ln(e3)62e^{3} + 4 + 3\ln(e^{3}) - 6.\newlineSince ln(e3)=3\ln(e^{3}) = 3 and ln(1)=0\ln(1) = 0, the expression further simplifies to:\newline2e3+4+962e^{3} + 4 + 9 - 6.
  9. Combine Like Terms: Combine like terms to get the final answer.\newline2e3+4+962e^{3} + 4 + 9 - 6 simplifies to:\newline2e3+72e^{3} + 7.
