Question

Which of the following terms in the expression $5y^2-11y+2yz-5z$ have "$y$" as a common factor?

• A. $2yz,-5z,5y^2$
• B. $5y^2,-11y,2yz$
• C. $2yz,-5z$
• D. $5y^2,-5z$

Answer 1

The correct option is B $5y^2,-11y,2yz$

$5y^2=5\times y\times y$
$-11y=-11\times y$
$2yz=2\times y\times z$
$-5z=-5\times z$

$\therefore 5y^2,-11y$ and $2yz$ have $y$ as a common factor.

So, option B is correct.
