Select ALL the expressions that are equivalent to the polynomial below.

(4x+5) (-3x-1)

(-16x^2 + 10x - 3) + (4x^2 - 29x - 2)

3 (x - 5) - 2 (6x^2 + 9x + 5)

2 (x - 1) - 3 (4x^2 + 7x + 1)

(2x^2 - 11x - 9) - (14x^2 + 8x - 4)

(-15x^2 + 9x - 10) + (3x^2 - 10x - 5)

    For this case we have the following polynomial:

    (4x + 5) ( - 3x-1)

    Rewriting we have:

    -12x ^ 2 - 4x - 15x - 5

    -12x ^ 2 - 19x - 5

    The equivalent polynomials for this case are given by:

    (-16x ^ 2 + 10x - 3) + (4x ^ 2 - 29x - 2)

    2 (x - 1) - 3 (4x ^ 2 + 7x + 1)

    (2x ^ 2 - 11x - 9) - (14x ^ 2 + 8x - 4)

    Answer:

    (-16x ^ 2 + 10x - 3) + (4x ^ 2 - 29x - 2)

    2 (x - 1) - 3 (4x ^ 2 + 7x + 1)

    (2x ^ 2 - 11x - 9) - (14x ^ 2 + 8x - 4)
