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

    =(x^2+2x+3x+6)(x-1)

    =(x^2+5x+6)(x-1)

    =(x^3+5x^2+6x-x^2-5x-6)

    =x^3+4x^2+x-6

    So yes you are right

    I hope that helps!

    Yes its true.

    Your question:

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

    First, multiply the first two parenthesis:

    = (x^2+3x+2x+6)(x-1)

    = (x^2+5x+6)(x-1)

    Then solve for the third parenthesis:

    = (x^3-x^2+5x^2-5x+6x-6)

    = (x^3-4x^2+x-6)

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

    (x+2)(x+3)= x^2 +5x +6 (x-1) =

    x^3 +4x^2 +x -6
