When you create an Easy Setup Key, the autorun.ini file on many flash drives is overwritten with the Linksys Wi-Fi Router or Linksys X-series Gateway program and settings. The autorun.ini file has instructions that tell your computer what programs to launch automatically.
The Discriminant. In the quadratic formula, the expression under the square root sign, b 2 â 4 ac, is called the discriminant. The sign of the discriminant can be used to find the number of solutions of the corresponding quadratic equation, ax 2 + bx + c = 0.If the discriminant b 2 â 4 ac is negative, then there are no real solutions of the equation.f the discriminant is positive, then the Â± symbol means you get two answers. The solutions of this equation correspond to the x-intercepts of the parabola. y = ax 2 + bx + c. So, you can also use the discriminant to find the number of x-intercepts of a parabola.
Quadratic Equations Review Matching Cards. Key Words: Quadratics, Roots, Completing the Square, Discriminant, Quadratic Graphs. This is a group-work matching activity covering everything to do with Quadratics. It takes about 2 lessons to do fully. Students need to match the equation to its roots, completed square form, discriminant, curve and find the coordinates of the minimum. Designed for and tested on top set Year 10 groups but would work equally well with year 12s for Core 1.
