<PRE><B>Question 204125</B>
f(x) =  -(2/3)*(x-1-sqrt(3))*(x-1+sqrt(3))
---
f(x) = (-2/3)*[(x-1)-sqrt(3))((x-1)+sqrt(3))]
----
Notice that that factors are now in the form (a-b)(a+b)
which multiplies to be a^2-b^2.
----
f(x) = (-2/3)*[(x-1)^2 -(sqrt(3))^2]
---
f(x) = (-2/3)*[x^2-2x+1 - 3]
---
f(x) = (-2/3)(x^2-2x-2)
