Simplify 8i^6+6i^5-5i^3-3i^2-7i-9

a) -14+4i b) -4+4i c) -10i d) -14-18i

The simplified form of complex expression is -14+4i

A is correct.

Step-by-step explanation:

Given:

As we know,

Put the value and simplify i

3

Combine the like term and simplify it

Hence, The simplified form of complex expression is -14+4i

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

a: inscribed angles
