Solving x^4-16=0

Here we will solve the 4th-degree polynomial equation x^4=16 by factoring. We will use the difference of two squares factoring formula twice, along with complex numbers! I will also show you how a geometric proof of why A^2-B^2=(A-B)(A+B). This question is from my Instagram: https://www.instagram.com/p/C3wQ0rWrx...
