Full solution

Q. x+1x1dx \int \frac{x+1}{\sqrt{x}-1} d x
  1. Rewrite Integral: Rewrite the integral by splitting the fraction into two parts.\newlinex+1x1dx=(xx1+1x1)dx\int\frac{x+1}{\sqrt{x}-1}\,dx = \int\left(\frac{x}{\sqrt{x}-1} + \frac{1}{\sqrt{x}-1}\right)dx
  2. Simplify First Term: Simplify the first term by multiplying the numerator and denominator by x+1\sqrt{x}+1 to rationalize the denominator.\newlinexx1dx=x(x+1)x1dx\int \frac{x}{\sqrt{x}-1}\,dx = \int \frac{x(\sqrt{x}+1)}{x-1}\,dx
  3. Simplify Expression: Simplify the expression.\newline\int\frac{x(\sqrt{x}+\(1\))}{x\(-1\)}\,dx = \int\frac{x^{\frac{\(3\)}{\(2\)}}+x}{x\(-1\)}\,dx
  4. Simplify Second Term: Now, let's simplify the second term by multiplying the numerator and denominator by \(\sqrt{x}+1.1x1dx=x+1x1dx\int \frac{1}{\sqrt{x}-1}\,dx = \int \frac{\sqrt{x}+1}{x-1}\,dx
  5. Combine Integrals: Combine the two integrals. \(\int\frac{x^{\frac{\(3\)}{\(2\)}}+x}{x\(-1\)}\,dx + \int\frac{\sqrt{x}+\(1\)}{x\(-1\)}\,dx
  6. Perform Integration: Perform long division or partial fraction decomposition for each term to integrate. This step is complex and requires careful algebraic manipulation.
