Answer 2

$Let us first factorize the numerator of the given division x+3x2+7x+12 as follows:</p><p></p><p> </p><p></p><p>x2+7x+12=x2+4x+3x+12=x(x+4)+3(x+4)=(x+3)(x+4)</p><p></p><p></p><p>Since we have to divide x+3x2+7x+12, therefore, we will divide x+3(x+3)(x+4) as shown below:</p><p></p><p></p><p>x+3(x+3)(x+4)=x+4</p><p></p><p></p><p>Hence, x+3x2+7x+12=x+4.</p><p>$
