Help simplify
![The image displays a mathematical expression involving complex numbers. It is labeled with the number 5 and represents a division problem of two complex numbers:
\[
\frac{1 - 3i}{1 + 2i}
\]
This expression is typically encountered in mathematics when dividing complex numbers. The goal might be to simplify the expression or express it in the standard form of a complex number, \(a + bi\), where \(a\) and \(b\) are real numbers, and \(i\) is the imaginary unit with the property \(i^2 = -1\).
**Explanation:**
To simplify this expression, one would typically multiply the numerator and the denominator by the complex conjugate of the denominator. The complex conjugate of \(1 + 2i\) is \(1 - 2i\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F41a94607-ae05-49d2-a989-bd66a70c4a42%2F91d098b7-1cfd-4b08-87cb-557f529b0f82%2Fxvpmey_processed.jpeg&w=3840&q=75)
