Question

factorise 2x^3+ x^2 - 13 x + 6​

Answer 1

$2 {x}^{3} + {x}^{2} - 13x + 6 \\ 2 {x}^{3} - 4 {x}^{2} + 5 {x}^{2} - 10x - 3x + 6 \\ \\ 2 {x}^{2}(x - 2) + 5x(x - 2) - 3(x - 2) \\ (x - 2)(2 {x}^{2} + 5x - 3) \\ (x - 2)(2 {x}^{2} - x + 6x - 3) \\ (x - 2)(x(2x - 1) + 2(x - 1)) \\ (x - 2)(2x - 1)(x + 2)$

Answer 2

Answer:

(x-2)(2x-1)(x+2)
