Answer:
-(y + x/5.
Step-by-step explanation:
y^2-x^2/5x-5y
The numerator is the difference of 2 squares so
= (y - x)(y + x) / 5(x - 5y)
The GCF of the denominator = 5 so we have:
(y - x)(y + x) / 5(x - y)
= (y - x)(y + x) / -5(y - x)
Now y - x is common to both numerator and denominator
so the answer is
(y + x)/-5.
= -(y + x)/ 5
