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.

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