Answer:
Let x and y be the two numbers. Then
yx=57 and x−y=20
Cross multiplying the proportion
5x=7y or y=75x
So, x−y=20
x−75x=20⇒77x−5x=72x=20
⇒x=2140=70
y=75x=75×70=50
So smaller number is 50.
Check :yx=5070=57 and 70−50=20

To factor a number out of an expression means to divide each term of the expression by that number.
So, if you want to factor
from the expression
, you'll write it as

So, in your case, when you divide both terms by -5 you get

So, the expression becomes
