solve this urgent plz​

Answer 1

$\sf \: Answer$

Worth to be noted that in the above equation which seems to be rather complicated (only seems xD) contains just two terms separated by the sign of subtraction.

$\sf(8 {t} - u)(t + 9u) - t(2u - 27) \\ \sf \: 8 {t}^{2} + 72ut - ut - 9 {u}^{2} - 2ut + 27t \\ \sf = 8 {t}^{2} - 69ut - 9 {u}^{2} + 27t$

Hence solved xD
