Media Summary: In this video we learn how to apply Quadratic Mean - Arithmetic Mean Inequality in the context of a Regional Hi guys so in this video I am going to go through the solutions to the (x²-2)²=x+2 → Find all real x Let y=x²-2. The equation becomes y²=x+2. Now write both equations side by side: y²-x=2 and x²-y=2.
