Question

factorise 2x^3 - 7x^3 + 2x + 3​

Answer 1

Answer:

$2 {x}^{3} - 7 {x}^{2} + 2x + 3 =$

$2 {x}^{3} - 2 {x}^{2} - 5 {x}^{2} + 5x - 3x + 3 =$

$2 {x}^{2} (x -1) - 5x(x - 1) - 3(x - 1) =$

$(x - 1)(2 {x}^{2} - 5x - 3) =$

$(x - 1)(2 {x}^{2} - 6x + x - 3) =$

$(x - 1)(2 x(x - 3) + 1(x - 3)) =$

$(x - 1)(x - 3)(2x + 1)$
