Question

$\text{Which of the following is the irreducible}\text{form of}12a(a+2)?$

• A. $2\times 6\times a\times (a+2)$
• B. $3\times 4\times a\times (a+2)$
• C. $2\times 2\times 3\times a\times (a+2)$
• D. $2\times 6\times a(a+2)$

Answer 1

The correct option is C $2\times 2\times 3\times a\times (a+2)$

$\text{Given, the expression is}12a(a+2).$

$\text{The above expression can be}\text{factorized as,}12a(a+2)$
$=2\times 2\times 3\times a(a+2)$
$=2\times 2\times 3\times a\times (a+2)$
