4x^2 = 2 * 2 * x * x
14x(x + 2)
x2-10x-24 = (x+2)(x-12) when factored
Assuming that is x squared minus 16: x2 - 16 = (x + 4)(x - 4) (The difference of two squares.)
Think of their prime factorizations. A squared number will always have paired prime factors. When they have no prime factors in common, like 4 (2 x 2) and 9 (3 x 3), the LCM will be their product, 2 x 2 x 3 x 3 or 36 (6 squared). When they have prime factors in common, like 36 (2 x 2 x 3 x 3) and 225 (3 x 3 x 5 x 5), the LCM will still have paired factors: 2 x 2 x 3 x 3 x 5 x 5 or 900 (30 squared)
