factorable quadratic equation and solve for the roots: 2x^2 + 13x + 20=0

  • math -

    In google type:

    quadratic equation online

    When you see list of results click on:

    Free Online Quadratic Equation Solver:Solve by Quadratic Formula

    When page be open click option

    Solve by Factoring (includes Factoring by Grouping)

    then in rectangle type

    2x^2 + 13x + 20=0

    and click option

    solve it

  • math -

    the 13x in the middle indicates you will need 5 as one of the factors of 20, and it cannot be multiplied by 2, so

    (2x+5)(x+4)
