Ohh. Thanks sir.  I did:   ((t/(t  +  2)))^2   +   ((2/(t  +  2)))^2    =   ((52)/(100))
$$\mathrm{Ohh}.\:\mathrm{Thanks}\:\mathrm{sir}. \\ $$$$\mathrm{I}\:\mathrm{did}:\:\:\:\left(\frac{\mathrm{t}}{\mathrm{t}\:\:+\:\:\mathrm{2}}\right)^{\mathrm{2}} \:\:+\:\:\:\left(\frac{\mathrm{2}}{\mathrm{t}\:\:+\:\:\mathrm{2}}\right)^{\mathrm{2}} \:\:\:=\:\:\:\frac{\mathrm{52}}{\mathrm{100}} \\ $$
