EITHER State or imply non-modular inequality ${\left( {x + 2} \right)^2} > {\left( {\frac{1}{2}x - 2} \right)^2}$, or corresponding equation or pair of linear equations

Make reasonable solution attempt at a 3-term quadratic, or solve two linear equations

Obtain critical values $ - 8$ and $0$

State correct answer $x \lt  - 8$ or $x \gt 0$

OR Obtain one critical value, e.g. $x =  - 8$, by solving a linear equation (or inequality) or from a graphical method or by inspection

Obtain the other critical value similarly

State correct answer $x \lt  - 8$ or $x \gt 0$
