Algebra 2 - Learn how to divide a real number by a complex number by simplifying, -3/(5 + i)

The video tutorial explains the process of handling expressions with imaginary numbers, specifically focusing on why multiplying by i doesn't eliminate it from the denominator. It introduces the concept of using the conjugate to remove i from the denominator and demonstrates the simplification of expressions using the difference of squares. The tutorial concludes by converting expressions into the standard form a plus bi, emphasizing the use of the distributive property in both multiplication and division.
