    Answer is = 2x^3+3x^2-11x-6

    Step-by-step explanation:

    First of all multiply first and second bracket.

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

    =2x^2+x-4x-2

    =2x^2-3x-2

    Now multiply 2x^2-3x-2 with (x+3)

    =x (2x^2-3x-2) + 3 (2x^2-3x-2)

    =2x^3-3x^2-2x+6x^2-9x-6

    =2x^3+3x^2-11x-6
