Question

$3xx + 9x + 6$
​

Answer 1

$Given \: Quadratic \: expression :$

$3x^{2} + 9x + 6$

/* Splitting the middle term, we get */

$= 3x^{2} + 3x + 6x + 6$

$= 3x(x+1)+6(x+1)$

$= (x+1)(3x+6)$

$= (x+1)[3(x+2)]$

$= 3(x+1)(x+2)$

Therefore.,

$\red{ Factors \:of \: 3x^{2} + 9x + 6}$

$\green {= 3(x+1)(x+2)}$
