From Math Queen.

In this math video I (Susanne) explain how to calculate squre roots correctly. Many people believe √4 equals ±2, but that’s a common math mistake! In this video, I explain why the square root is always positive, when negative solutions appear, and how to solve quadratic equations step by step. Mathematics explained.
