B. Use the given factor or factors to completely factor the polynomial.
1. f(x)=x²-x² - x - 2; x - 2
2. f(x) = x - x² – 11x +15; x-3
3. f(x)=2x3 + x² – 29x – 28; x +1
4. f (x) = 4x* – 51x2 +49x – 12; (2x - 1)?
5. f(x)=x* +6x* – 3x? – 22x – 24; x +6

please help me to solve this i need the answer ASAP
