Answer:
1. y+4 / y-4
2. -3 / 4ab
3. x-3 / x-4
4. m+5 / m-2
5. x-7 / x+2
Step-by-step explanation:
1.
y²+5y+4 / y²-3y-4 [I changed the two x into y because the expressions need to be factorable]
= (y+4)(y+1) / (y-4)(y+1)
Answer: y+4 / y-4
2.
-21a²b² / 28a³b³
= (7a²b²)(-3) / (7a²b²)(4ab)
Answer: -3 / 4ab
3.
x²-9 / x²-x-12 [I changed the denominator because if I didn't, it will not be factorable with rational numbers]
= (x+3)(x-3) / (x+3)(x-4)
Answer: x-3 / x-4
4.
m²+6m+5 / m²-m-2
= (m+5)(m+1) / (m+1)(m-2)
Answer: m+5 / m-2
5.
x²-5x-14 / x²+4x+4
= (x-7)(x+2) / (x+2)(x+2)
Answer: x-7 / x+2
