a) x2 – 2xy + y2
(x–y) (x-y)
c) x2 + 2x + 1 =
(x+y) (x+y)
e) - 2xy2 + 16x2 =
2x(y2+ 8x)
b) 2y2 + y4 + 1 = (y2+1)2
c) x2 + 2x + 1 = (x+1)2
d) a6 – 8a3 + 16 = (a3-4)2
e) - 2xy2 + 16x2 = (3-y)2? <=esta no estoy muy segura, las otras estan hasta verificadas
f) 4− 4 (1 – a) + (1 – a)2 = 9-6a+a = (3-a)2
g) 9x2 – 6x (x – y) + (x – y)2 = 4x2+4xy+y2 = (2x+y)2
h) 49x2 – 14x + 1 = (7x-1)2
i) (a – b)2 + 2 (a + b) (a – b) + (a + b)2 = a2-2ab+b2+2a2-2b2+a2+2ab+b2 = 4(a+b)(a-b)
j) 9x2 – 12xy + 4y2 = (3x-4y)2
