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.
Summary. 1  Quadratic Equation in Standard Form: ax 2 + bx + c = 0. 2  Quadratic Equations can be factored. 3  Quadratic Formula: x = [ -b Â± â(b2-4ac) ] / 2a. 4  When the Discriminant (b2-4ac) is: 5  positive, there are 2 real solutions. 6  zero, there is one real solution. 7  negative, there are 2 complex solutions.
