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: (frac(4)(3)m -frac(3)(4)n)^2 + 2mn = frac(16)(9) m^2 + frac(9)(16)n^2

Show that: (4/3m-3/4n)^2 +2mn=(16)/9m^2+9/16n^2

Show that ((4m)/3-(3n)/4)^2 +2mn = 16/9m^2+9/16 n^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)
