Question

59. If p(x) = (x - 1)(x + 2), then we say, (a) (x - 1) is a factor of p(x) - a (b) (x + 2) is a factor of p(x) (c) p(x) is divisible by both (x - 1) and (x + 2) (d) All of these​

Answer 1

Answer:

answer d

Step-by-step explanation:

because all are true

Answer 2

Answer:

(d)

Step-by-step explanation:

x-1 or x=1

p(1)= (1-1)(1+2)

=. (0)(3)

= 0

same applies for option B

obliviously p(x) is divisible by (x-1) and (x+1)

so answer is option D
