Answer 1

p(x) = 2x3 + 7x2 - 3x - 18

consider, p(1) = 2 + 7 - 3 - 180

p(-1) = -2 + 7 + 3 - 180

p(2) = 16 + 28 - 6 - 180

p(-2) = -16 + 28 + 6 - 18 = 0

(x + 2) is a factor of p(x).

p(x) = (x + 2) (2x2 + 3x - 9)

= (x + 2) (2x2 + 6x - 3x - 9)

= (x + 2) (2x (x + 3) - 3 (x + 3)

= (x + 2) (x + 3) (2x - 3)
