here,

putting m = 2 ,

$= > {2m}^{2} - 5m = 00$

$= > 2 \times {2}^{2} - 5 \times 2$

$= > 2 \times 4 - 10$

$= > - 2$

left hand side is not equal to right hand side....

hence,

putting

$m = \frac{5}{2}$

$= > {m}^{2} - 5m = 00$

$= > 2 \times \frac{5}{2}^{2} - 5 \times \frac{5}{2}$

$= > \frac{25}{2} - \frac{25}{2} = 00$

here,

left hand side is equal to right hand side...
