A= ( x+3) ²
A = x² +6x +9
B= (x+8) ²
B = x² +16x +64
C= (x +12)²
C = x² +24x +144
D = (x-5)²
D = x² -10x +25
E= (x-2)²
E = x² -4x +4
F= (x-9) ²
F = x² -18x +81
G = (x+7) (x-7)
G = x² -49
H = (x-6) (x+6)
H = x² -36
I = (x+1)²
x² +2x +1
J = (x+5) (x-5)
J = x² -25
K = (4-x)²
K = 16 -8x +x²
L= (x -2,5)²
L = x² -5x +6,25
M = (6+x) ²
M = 36 +12x +x²
N = (1-x) (1+x)
N = 1 -x²
O = (x-3) (x+3)
O = x² -9
