(3d3 - 5d2x3)2 = (3d3)2 - 2*(3d3)*(5d2x3) + (5d2x3)2 = 9d6 - 30d5x3 + 25d4x6
(b4 + 9bk4)2 = (b4)2 + 2*(b4)*(9bk4) + (9bk4)2 = b8 + 18b5k4 + 81b2k8
(r2 - 4ry3)2 = (r2)2 - 2*(r2)*(4ry3) + (4ry3)2 = r4 - 8r3y3 + 16r2y6
(4b4 - 5bu2)2 = (4b4)2 - 2*(4b4)*(5bu2) + (5bu2)2 = 16b8 - 40b5u2 + 25b2u4
(d4 + dz4)2 = (d4)2 + 2*(d4)*(dz4) + (dz4)2 = d8 + 2d5z4 + d2z8
(4g2 + 8gv2)2 = (4g2)2 + 2*(4g2)*(8gv2) + (8gv2)2 = 16g4 + 64g3v2 + 64g2v4
(8d3 - dx3)2 = (8d3)2 - 2*(8d3)*(dx3) + (dx3)2 = 64d6 - 16d4x3 + d2x6
