what is the fact of

  • MATH -

    since, it's not factorable, use qudratic formula:
    x = [-b +- sqrt(b^2-4ac)]/(2a)
    where a=2, b=34, c=-141
    x = [-34 +- sqrt(1156-4*2*(-141)]/(2(2))
    x = [-34 +- 2*sqrt(571)]/4

    x = (1/2)(-17-sqrt(571)) ; and
    x = (1/2)(-17+sqrt(571))

    so there,, :)
