If one solution is -3-5i then the other solution will be -3+5i
So, Option A is correct.
Step-by-step explanation:
We need to find the other solution of the quadratic function, when one solution is -3-5i
The quadratic equation is of the form: 
The complex roots of the quadratic equation are of form: 
So, if one solution is -3-5i then the other solution will be -3+5i
So, Option A is correct.

Answer:
During the first year he had an annual interest of 12%, and in the second year of 25%
Step-by-step explanation:
To calculate the interest of the first year:
(Initial capital of the first year / final capital of the first year) - 1 = interest of the first year
(300/336) - 1 = 0.12 = 12%
To calculate the interest of the second year:
(Initial capital of the secondyear / final capital of the second year) - 1 = interest of the second year
(336/420) - 1 = 0.25 = 25%
