MCQ
Factorised form of $p^2 - 17p - 38$ is:
- ✓$(p - 19)(p + 2)$
- B$(p - 19)(p - 2)$
- C$(p + 19)(p + 2)$
- D$(p + 19)(p - 2)$
✓
Answer
Correct option: A.
$(p - 19)(p + 2)$
A. $(p - 19)(p + 2)$
Solution:
We have,
$p^2- 17p - 38$
$= p^2 - 19p + 2p - 38$
$= p(p - 19) + 2(p - 19)$
$= (p - 19)(p + 2)$
Solution:
We have,
$p^2- 17p - 38$
$= p^2 - 19p + 2p - 38$
$= p(p - 19) + 2(p - 19)$
$= (p - 19)(p + 2)$
