Question
Factorise:
$3m^2+ 24m + 36$
$3m^2+ 24m + 36$
✓
Answer
$ 3 m^2+24 m+36 $
$ =3\left(m^2+8 m+12\right) $
$ =3\left(m^2+6 m+2 m+12\right) $
$ \{12=6 \times 2,8=6+2\} $
$ =33(m+6)+(m+2) $
$ =(2 x-3)(3 x+2) $
$ =3\left(m^2+8 m+12\right) $
$ =3\left(m^2+6 m+2 m+12\right) $
$ \{12=6 \times 2,8=6+2\} $
$ =33(m+6)+(m+2) $
$ =(2 x-3)(3 x+2) $
