Answer 1

Hey !!!! ^_^

Here is your answer

⬇️⬇️⬇️⬇️⬇️⬇️
${2x}^{3} - {3x}^{2} - 17x + 30 \\ \\ {2x}^{3} - {4x}^{2} + {x}^{2} - 2x - 15x + 30 \\ \\ {2x}^{2} (x - 2) + x(x - 2) - 15(x - 2) \\ \\ (x - 2)( {x}^{2} + x - 15) \\ \\ and \\ \\ now... \\ \\ {2x}^{2} + x - 15 \\ \\ {2x}^{2} + 6x - 5x - 15 \\ \\ 2x(x + 3) - 5(x + 3) \\ \\ (2x - 5)(x + 3) \\ \\ therefore \: the \: fctorisation \\ (x - 2)(2x - 5)(x + 3)$


I HOPE IT WILL HELP YOU ☺️✌️
