\frac{x\left(x-\left(\sqrt{2}-1\right)\right)\left(x-\left(-\sqrt{2}-1\right)\right)\left(x^{2}-2x+5\right)}{x^{2}-2x+5}
Factor the expressions that are not already factored.
x\left(x-\left(\sqrt{2}-1\right)\right)\left(x-\left(-\sqrt{2}-1\right)\right)
Cancel out x^{2}-2x+5 in both numerator and denominator.
x^{3}+2x^{2}-x
Expand the expression.
