Restlessness and depression could have surely been a result in either of these situations. Cabin fever is such a universal affliction that movies and books have dramatized its sometimes horrifying effect on people and their mental state. Stephen Kingâs The Shining is a good example of how isolation can drive a person mad.
The Quadratic Formula: For ax2 + bx + c = 0, the value of x is given by: The nice thing about the Quadratic Formula is that the Quadratic Formula always works. There are some quadratics (most of them, actually) that you can't solve by factoring.
Solving Quadratic Equations: Solving by Factoring (page 1 of 6). Sections: Solving by: factoring, taking roots, completing the square, using the formula, graphing. This lesson covers many ways to solve quadratics, such as taking square roots, completing the square, and using the Quadratic Formula. But we'll start with solving by factoring. You should already know how to factor quadratics. (If not, review Factoring Quadratics .) The new thing here is that the quadratic is part of an equation, and you're told to solve for the values of x that make the equation true.
