Answer:
xy(y - x)(y + x)
Step-by-step explanation:
take out a common factor xy from both terms
= xy(y² - x²)

Hence
xy³ - x³y = xy(x - y)(x + y)
Answer:
or ![(-\infty, 47/6]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%2047%2F6%5D)
Step-by-step explanation:
Note that 
.
Also, note that 
.
So, the inequality is really equal to 
.
We can then add 
to both sides to get .
So, the solution is , or in interval notation,
52 = 50
512= 500
500/50 = 10
