MCQ
The factors of $3m^2 + 9m + 6$ are:
- A$(m + 1) (m + 2)$
- ✓$3(m + 1) (m + 2)$
- C$6(m + 1) (m + 2)$
- D$9(m + 1) (m + 2)$
✓
Answer
Correct option: B.
$3(m + 1) (m + 2)$
B. $3(m + 1) (m + 2)$
Solution:
$= 3m^2 + 9m + 6 = 3(m^2 + 3m + 2)$
$= 3 (m^2 + m + 2m + 2)$
$= 3m(m + 1) + 2( m + 1)$
$= 3(m + 1) (m + 2)$
Solution:
$= 3m^2 + 9m + 6 = 3(m^2 + 3m + 2)$
$= 3 (m^2 + m + 2m + 2)$
$= 3m(m + 1) + 2( m + 1)$
$= 3(m + 1) (m + 2)$
