10 xy + 3y + 20 ax + 6a = y(10x+3) + a(20x+6) = y(10x+3)+2a(10x+6)= 
(y+2a)(10x+3)

Answer:

Option 3 is correct.

Step-by-step explanation:

The given expression is

\(10xy+3y+20ax+6a\)

This expression can be written as

\((10xy+3y)+(20ax+6a)\)

Take out the common factors from each parenthesis.

\(y(10x+3)+2a(10x+3)\)

Now, take out the common factor (10x+3).

\((10x+3)(y+2a)\)

Therefore option 3 is correct.
