Answer:
1. 2m
2. a
3. 1/x-5
Step-by-step explanation:
B.
1. 4m²/2m
- Reduce the fraction with 2
2m²/m
- Simplify the expression
- 2m
2. abc/bc
- Reduce the fraction with b
ac/c
- Reduce the fraction with c
- a
3. x + 1/x² - 4x - 5
- Write -4x as a difference
x+1/x²+x-5x-5
- Factor out x from the expression
x+1/x x(x+1)-5x-5
- Factor out -5 from the expression
x+1/x x(x+1)-5(x+1)
- Factor out x+1 from the expression
x+1/(x+1)x(x-5)
- Reduce the fraction with x+1
1/x-5
