#1**+2 **

4x(5+-2)squared-2x4squared

It is not an equation becasue there is no equal sign but I can simplify it for you.

\(4\times (5+-2)^2-2 \times 4^2\\ =4\times (5-2)^2\;\;\;-\;\;\;2 \times 4^2\\ =4\times (3)^2\;\;\;-\;\;\;2 \times 4^2\\ =4\times 9\;\;\;-\;\;\;2 \times16\\ =36\;\;\;-\;\;\;32\\ =4\)
