Since , Given data states that 2x-1 and x + 3 are the factors ,
There multiple will also be a factor , hence ,
2x-1 ( x +3 ) = 2x² +5x - 3 will also satisfy the previous equation subsequently :
By dividing 2x³ + 13x² + 17x -12 by 2x² + 5x -3 we obtain remainder as 0 [ means complete division ] and quotient as x + 4
Hence , the 3rd factor is → x + 4
