Solve the equality.5(x^2-1)> -24x

  • College Algebra -

    (x^2-1) > -24/5 x
    x^2 + 24/25 x - 1 > 0
    x < (-12 - sqrt(769))/25
    x > (-12 + sqrt(769))/25

    Think of the parabola. Graph it and you want the part above the x-axis. That is the part extending left and right from the roots where x^2+24/25x-1=0
