I am still having trouble solving this problem.

Use the quadratic formula to solve this equation:

4k(k+13)=13

  • Algebra -

    4 k ( k + 13 ) = 13

    4 k * k + 4 k * 13 = 13

    4 k ^ 2 + 52 k = 13


    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 in rectangle type:

    4 k ^ 2 + 52 k = 13

    and click option: solve it

    You will see solution step-by step





    P.S.

    ( 1 / 8 ) ( - 52 )

    = 1 * ( - 52 ) / 8 =

    - 52 / 8 =

    - 13 * 4 / ( 2 * 4 ) = - 13 / 2



    ( 1 / 8 ) 4 sqrt ( 182 ) =

    4 sqrt ( 182 ) / 8 =

    ( 4 / 8 ) sqrt ( 182 ) =

    ( 1 / 2 ) sqrt ( 182 ) =

    ( 1 / 2 ) sqrt ( 4 * 91 / 2 ) =

    ( 1 / 2 ) sqrt ( 4 ) sqrt ( 91 / 2 ) =

    ( 1 / 2 ) * 2 * sqrt ( 91 / 2 ) =

    1 * sqrt ( 91 / 2 ) =

    sqrt ( 91 / 2 )
