Answer 2

X = 2 + 5i  is the expression is equal to (−3−i)+(5+6i).

Answer - (Option A)

Given:

Expression is equal to (−3−i)+(5+6i)

To find:

The equivalent expression

Solution:  

Consider X =  (−3−i)+(5+6i)

The given expression is a complex number, hence the real and imaginary parts has to be segregated.

The parts with I is the imaginary part and the integers are the real part.

The square of i = -1

Simplifying, X =  (−3−i)+(5+6i)

X = 2 + 5i

This is the resultant expression.

Result:

X = 2 + 5i is the resultant expression.
