Pre-Calculus - Adding rational complex numbers- Online Math Tutor 2 / (1+i) - 3/(1-i)

The video tutorial explains how to subtract two rational expressions by rationalizing the denominator using conjugates. It covers finding a common denominator, simplifying the expression, and converting the result into standard form. The process involves using the distributive property and understanding complex conjugates as a difference of squares. The final result is expressed in standard form, demonstrating the importance of combining real and imaginary parts separately.
