$\frac{}{\left(\sqrt{x^{3}-2x+6}-\sqrt{\left(x+1\right)^2+5}\right)\left(x-3\right)\left(x-1\right)}$

## Step-by-step explanation

Problem to solve:

$\frac{\frac{}{\sqrt{x x^2-2x+6}-\sqrt{x^2+2x+6}}}{x^2-4x+3}$
1

When multiplying exponents with same base you can add the exponents

$\frac{\frac{}{\sqrt{x^{3}-2x+6}-\sqrt{x^2+2x+6}}}{x^2-4x+3}$
2

Simplifying the fraction

$\frac{}{\left(\sqrt{x^{3}-2x+6}-\sqrt{x^2+2x+6}\right)\left(x^2-4x+3\right)}$

$\frac{}{\left(\sqrt{x^{3}-2x+6}-\sqrt{\left(x+1\right)^2+5}\right)\left(x-3\right)\left(x-1\right)}$
