I need to factor this trinomial,
but I can't figure it out.

2q²-9q-18

  • 9th grade math -

    (2q+3)(q-6) , i just think of it was you know the 2q and q because of 2q^2. and you know the last two have to multiply to be 18

  • 9th grade math -

    3 * 6 = 18

    2 * 6 = 12

    12 - 3 = 9

    This can lead you to John's answer.
