F = x^2 + 10x + 25
F = x^2 + 2 * x * 5 + 5^2
F = (x + 5)^2
G = (x + 5)^2 - 4
G = (x + 5)^2 - 2^2
G = (x + 5 - 2)(x + 5 + 2)
G = (x + 3)(x + 7)
H = (x - 1)^2 + (x - 1)(x + 3)
H = (x - 1)(x - 1 + x + 3)
H = (x - 1)(2x + 2)
H = (x - 1) * 2(x + 1)
H = 2(x - 1)(x + 1)
I = 25x^2 - 20x + 16
I = (5x)^2 - 2 * 5x * 2 + 2^2 + 12
I = (5x - 2)^2 + 12
J = 18x^2 + 24x + 8
J = 2(9x^2 + 12x + 4)
J = 2[(3x)^2 + 2 * 3x * 2 + 2^2]
J = 2(3x + 2)^2
