Answer:

(x-1)^3(26+15\sqrt{3})

Step-by-step explanation:

We substitute for x:

((x-1)/(2-√3))^3

We cube 2-√3

(2-\sqrt{3})^3\\=8-12(\sqrt{3} )+18-(3\sqrt{3})\\ =26-15\sqrt{3}

Therefore we can write the fraction

(x-1)^3/(26-15\sqrt{3})

Since we can't have a sqrt on the bottom we multiple the opposite (26+15\sqrt{3})

Therefore we get (x-1)^3(26+15\sqrt{3}})
