If `x=-5+2sqrt(-4)` , find the value of `x^4+9x^3+35 x^2-x+4.`

Explanation

To find the value of the expression \( x^4 + 9x^3 + 35x^2 - x + 4 \) given \( x = -5 + 2\sqrt{-4} \), we can follow these steps:

### Step 1: Simplify \( x \)
Given:
\[ x = -5 + 2\sqrt{-4} \]
We can simplify \( \sqrt{-4} \):
