d) (6x – 2y)2 = e) (5x – 4)2 = f) (11n + 8)2 =
g) (5x – y).(5x + y)= h) (x – 4y).(4y + x)= i) (y + 2x).(2x – y)= j) (x3 – 3y).(3y + x3)=

Answer 1

A)(3x + 8)2 =  9x2 +48x + 64
b) (4m – 5)2 = 16m2 - 40m + 25
c) (x – 6y)2 = x2 - 12xy + 36y2
d) (6x – 2y)2 =  36x2 - 24x + 4 
e) (5x – 4)2 = 25x2 - 40x + 16
f) (11n + 8)2 = 121n2 + 176n + 64
g) (5x – y).(5x + y)= 25x2 - y2
h) (x – 4y).(4y + x)= x2 - 16y2
i) (y + 2x).(2x – y)= y2 - 4x2
j) (x3 – 3y).(3y + x3)= x6 - 9y2
