1. SOLUTION:(x + 3)³ = x³ + 3(x)²(3) + 3(x)(3)² + 3³(x + 3)³ = x³ + 9x² + 3x(9) + 27(x + 3)³ = x³ + 9x² + 27x + 272. SOLUTION:(x - 4)³ = x³ - 3(x)²(4) + 3(x)(4)² - 4³(x - 4)³ = x³ - 12x² + 3x(16) - 64(x - 4)³ = x³ - 12x² + 48x - 643. SOLUTION:(x + 10)³ = x³ + 3(x)²(10) + 3(x)(10)² + 10³(x + 10)³ = x³ + 30x² + 3x(100) + 1000(x + 10)³ = x³ + 30x² + 300x + 1000
