MCQ
$6x^2 + 17x + 5 = ?$
- A$(2x + 1)(3x + 5)$
- ✓$(2x + 5)(3x + 1)$
- C$(6x + 5)(x + 1)$
- DNone of these
✓
Answer
Correct option: B.
$(2x + 5)(3x + 1)$
$6x^2 + 17x + 5$
$= 6x^2 + 15x + 2x + 5$
$= 3x(2x + 5) + 1(2x + 5)$
$= (2x + 5)(3x + 1)$
$= 6x^2 + 15x + 2x + 5$
$= 3x(2x + 5) + 1(2x + 5)$
$= (2x + 5)(3x + 1)$
