Question

Factorised form of p²– 17p – 38 is
(a) (p – 19) (p + 2)
(b) (p – 19) (p – 2)
(c) (p + 19) (p + 2)
(d) (p + 19) (p – 2)

Solution

Factorise the given expression
$p^{2} - 17 p - 38$
use middle term splitting
$= p^{2} + 2 p - 19 p - 38 = p (p + 2) - 19 (p + 2) = (p - 19) (p + 2)$
Hence option(A) is correct
