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)

Answer 1

(a) (p – 19) (p + 2)

Factorised form of p² – 17p – 38 is = p² – 19p + 2p – 38

Take out the common factors,

= p (p – 19) + 2 (p – 19)

Again take out the common factor,

= (p – 19) (p + 2)
