Question

Factorise:2x^3-9x^2+x+12

Answer 1

question is wrong my freind

Answer 2

p(x) =
$2 {x}^{3} - 9 {x}^{2} + x + 12$
p(-1) = 0
so x+1 is a factor of this polynomial

this polynomial divided by x+1
$2 {x}^{2} - 11x + 12$
factories it
$2 {x}^{2} - 8x - 3x + 12$
2x(x-4) -3(x-4)
(x-4) (2x-3)

hence factor (x+1) (x-4) (2x-3)
