Question

factorise 2x^3 - 3x^2 - 17x + 30​

Answer 1

$2 {x}^{3} - 3 {x}^{2} - 17x + 30 \\ 2 {x}^{3 } - 4 {x}^{2} + {x}^{2} - 2x - 15x + 30 \\ 2 {x}^{2} (x - 2) + x(x - 2) - 15(x - 2) \\ (x - 2)(2 {x}^{2} + x - 15) \\ (x - 2)(2 {x}^{2} + 6x - 5x - 15) \\ (x - 2)(2x(x + 3) - 5(x + 3)) \\ (x - 2)(2x - 5)(x + 3)$
