" (i) "(3x+7)^(2)-84x=(3x-7)^(2)

Show that: :(3x+7)^(2)-84x=(3x-7)^(2)(9a-5b)^(2)+180ab=(9a+5b)^(2)((4m)/(3)-(3n)/(4))^(2)+2mn=(16m^(2))/(9)+(9n^(2))/(16)

Show that (3x+7)^2-84x = (3x-7)^2

Show that: (3x + 7)^2 - 84x = (3x - 7)^2

Show that : (3x+7)^2-84 x=(3x-7)^2 (9a-5b)^2+180 a b=(9a+5b)^2 ((4m)/3-(3n)/4)^2+2m n=(16 m^2)/9+(9n^2)/(16)

Show that: (3x + 7)^2 – 84x = (3x – 7)^2

Show that : (3x-7)^2 +84x=(3x+7)^2 .
