Dear Student
(2.5l – 0.5m) and (2.5l + 0.5m)
= 2.5l * 2.5 l + 2.5l * 0.5m–0.5m * 2.5l - 0.5m * 0.5m
= 6.25l^2 + 1.25 lm–1.25 lm - 0.25 m^2
= 6.25l^2- 0.25 m^2
Thanks
(2.5l – 0.5m) and (2.5l + 0.5m)
= 2.5l * 2.5 l + 2.5l * 0.5m–0.5m * 2.5l - 0.5m * 0.5m
= 6.25l^2 + 1.25 lm–1.25 lm - 0.25 m^2
= 6.25l^2- 0.25 m^2
Thanks
