A= (2x + 3)2 + (2x + 3)(x + 2)
A = (2x + 3)(2x + 3 + x + 2)
A = (2x + 3)(3x + 5)
B = (4x – 5)(7x - 1) +(4x - 5)2
B = (4x - 5)(7x - 1 + 4x - 2)
B = (4x - 5)(11x - 3)
C = (2x - 1)2 + (2x - 1)(8x - 11)
C = (2x - 1)(2x - 1 + 8x - 11)
C = (2x - 1)(10x - 12)
C = (2x - 1) * 2(5x - 6)
C = 2(2x - 1)(5x - 6)
D= (2x + 5)(7x - 3)-(2x + 5)2
D = (2x + 5)(7x - 3 - 2x - 5)
D = (2x + 5)(5x - 8)
E = (x-8)(5 + 3x) - (x – 8)(7 - x)
E = (x - 8)(5 + 3x - 7 + x)
E = (x - 8)(4x - 2)
E = (x - 8) * 2(2x - 1)
E = 2(x - 8)(2x - 1)
F=(3 – 2x)(4x + 1) + 3(x + 1)(3 – 2x)
F = (3 - 2x)(4x + 1 + 3(x + 1))
F = (3 - 2x)(4x + 1 + 3x + 3)
F = (3 - 2x)(7x + 4)
G= (2x + 5)(7x - 1)+ 4x + 10
G = (2x + 5)(7x - 1) + 2(2x + 5)
G = (2x + 5)(7x - 1 + 2)
G = (2x + 5)(7x + 1)
H = (5x - 3)2 - 15x2
H = (5x - 3)^2 - (xV15)^2
H = (5x - 3 - xV15)(5x - 3 + xV15)
