A = - 2.585 , B = - 119.5 , C = 16512.615 , D = 175875.773 , E = 66.138

The given equation from the image is:

\[
A z_1^4 + B z_1^3 + C z_1^2 + D z_1 + E = 0
\]

with the coefficients provided as:

- \( A = -2.585 \)
- \( B = -119.5 \)
- \( C = 16512.615 \)
- \( D = 175875.773 \)
- \( E = 66.138 \)

Let's substitute these values into the equation and solve for \( z_1 \):

\[
-2.585 z_1^4 - 119.5 z_1^3 + 16512.615 z_1^2 + 175875.773 z_1 + 66.138 = 0
\]

I'll find the roots of this quartic equation now.The roots of the given quartic equation are approximately:

1. \( z_1 \approx -102.212 \)
2. \( z_1 \approx 66.060 \)
3. \( z_1 \approx -10.076 \)
4. \( z_1 \approx -0.000376 \)
