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:
Correct option is (a)
Given, p² - 17p - 38
On factoring this polynomial, we get
= p² - 19p + 2p - 38
= p(p - 19) + 2(p -19)
= (p + 2) (p - 19)
✦ Try This: Factorised form of x² - 16x + 63 is (a) (x - 7)(x + 9), (b) (x - 7)(x - 9), (c) (x + 7)(x - 9), (d) (x + 7)(x + 9)
Correct option is (b)
Given, x² - 16x + 63
= x² - 9x - 7x + 63
= x( x - 9) - 7(x - 9)
= (x - 7)(x - 9)
