Using factor theorem, show that polynomial g(x) is a 1. f(x) = x3 + x2 - 17x + 15; g(x) = x - 3 2. f(x) = x3 - 5x2 + 2x + 8; g(x) = x - 2 3. f(x) = 2x3 + 4x + 6; 8(x) = x + 1 4. f(x) = x3 – x2 - (2 + 2)x - 72;8(x) = x + 1 5. f(x) = x3 + 3x2 + 3x + 2; g(x) = x + 2 6. f(x) = 2x² – 3x2 – 3x – 5;8(x) = 2x - 5 7. f(x) = 6x3 + 31x2 + 3x - 10; 8(x) = 3x + 2 .f(x) = 2 V2 x2 + 5x + V2; 8(x) = x + V2 f(x)...
