As x ranges over all real values, what is the minimum value of the polynomial x4−14x2+303?

  • Math (Algebra) - , Wednesday, May 1, 2013 at 2:31pm

    If you let u=x^2, you have
    u^2 - 14u + 303 = (u-7)^2 + 254

    That's just a parabola with vertex at (7,254)

    So, the minimum occurs at x=±√7 and is 254.
