Solution

The correct options are
A
2

B
y

The expression $2 x y + 6 y^{2}$ can be written as,

$= 2 \times x \times y + 2 \times 3 \times y \times y$

Taking $2 y$ common, we get

$= 2 y (x + 3 y)$

$\Rightarrow$ $2 x y + 6 y^{2} = 2 y (x + 3 y)$

Therefore, the common factors of $2 x y + 6 y^{2}$ are $2 y$ and $(x + 3 y)$ .

The common factors of 2xy+6y2 are:

The correct options are A 2 B y The expression 2xy+6y2 can be written as, =2×x×y+2×3×y×y Taking 2y common, we get =2y(x+3y) ⇒ 2xy+6y2=2y(x+3y) Therefore, the common factors of 2xy+6y2 are 2y and (x+3y).
