Question

$\text{Find the common factor in the expression:}4xy+8y.$

• A. $2x$
• B. $4x$
• C. $4y$
• D. $4xy$

Answer 1

The correct option is C $4y$

$\text{Given expression:}4xy+8y$

$\text{On factorizing each term of the}\text{given expression, we get}$

$4xy=2\times 2\times x\times y8y=2\times 2\times 2\times y$

$\text{The common factors are}\text{2, 2, y.}$

$\text{Hence, the common factor of the given}\text{expression is}2\times 2\times y=4y$
