Question #0aa4d

Answer 1

See below.

Explanation:

To find `a`, it appears that you'll need some way to solve the cubic equation that results from

`a/(2(a-1))+(a-1)^2 = 0`

`a+2(a-1)^3 = 0`

`2a^3-6a^2+7a-2=0`

Now you need the general method for solving a cubic or some approximation method or some technology to get a solution.
