Simplify<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B2%20%2B%20i%7D%20" id="TexFormula1" title=" \frac{4}{2 + i} "

Hey! Apologies that I can’t make this look nice because I’m on mobile.

To simplify this, we can multiply the denominator by its conjugate. For a imaginary function (a+bi), its conjugate would be (a-bi), so we can apply that here to multiply both sides by (2-i)/(2-i). This works because it simplifies to one. Then, we have our fraction as 4*(2-i)/((2-i)(2+i))=(8-4i)/(4-i^2)=(8-4i)/5

Feel free to ask further questions, and have a great rest of your day!
