1) 7(a + 4)(a - 4) = 7(a² - 16) = 7a² - 112
2) x(x - 7)(x + 7) = x(x² - 49) = x³ - 49x
3) 4b(b + 3)(3 - b) = 4b(9 - b²) = 36b - 4b³
4) 8c³(c - 5)(c + 5) = 8c³(c² - 25) = 8c⁵ - 200c³
5) -5d⁴(-d - 6)(d - 6) = -5d⁴(36 - d²) = -180d⁴ + 5d⁶
6) p²(p² + 1)(p - 1)(p + 1) = p²(p² + 1)(p² - 1) = p²(p⁴ - 1) = p⁶ - p²
7) (z + 2)(z - 2)(z² + 4) = (z² - 4)(z² + 4) = z⁴ - 16
8) (-t + 3)(-t - 3)(t² + 9) = (t² - 9)(t² + 9) = t⁴ - 81
9) (-10t² + 1)(10t² + 1)(100t⁴ + 1) = (1 - 100t⁴)(100t⁴ + 1) = 1 - 10000t⁸
10) 2(s² + 1)(s² - 1)(s⁴ + 1) = 2(s⁴ + 1)(s⁴ - 1) = 2(s⁸ - 1) = 2s⁸ - 2
11) p²(p² + 1)(p - 1)(p + 1) = p²(p² + 1)(p² - 1) = p²(p⁴ - 1) = p⁶ - p²
12) 3q³(q² + 4)(q² - 4)(q⁴ + 16) = 3q³(q⁴ + 16)(q⁴ - 16) = 3q³(q⁸ - 256) = 3q¹¹ - 768q³
