-7 and -4 the quadratic equation is?
Thank you in advance :)

    This makes no sense.

    do you mean

    (x+7)(x+4)=0 where the roots are -4,-7?

    FOIL it out.

  • Algebra -

    x=-7 and x=-4
    x+7=0 and x+4=0

    (x+7)(x+4) = x^2 + 4x + 7x +28

    the equation would be x^2 + 11x + 28

  • Algebra -

    correct
