	Quadratic equation Summary (Site not responding. Last check: )
		The theory involving quadratic equations, and all polynomial equations, was flawed prior to the 17th century because of this idea.
		In mathematics, a quadratic equation is a polynomial equation of the second degree.
		This equation may be resolved directly or with a simple substitution, using the methods that are available for the quadratic, such as factoring (also called factorising), the quadratic formula, or completing the square.

	GRAPHS OF QUADRATIC EQUATIONS
		Every quadratic equation has at most two solutions, but for some equations, the two solutions are the same number, and for others, there is no solution on the number line (because it would involve the square root of a negative number, which makes it imaginary).
		When you set the quadratic equation equal to zero, this represents the points where the parabola hits the x-axis (the x-intercepts, where y=0).
		Where the parabola hits on the x-axis is the solution(s) to the quadratic equation.

		So this means we are talking about an equation that is a constant times the variable squared plus a constant times the variable plus a constant equals zero, where the coefficient a on the variable squared can't be zero, because if it were then it would be a linear equation.
		is the standard form for a quadratic equation, and for future reference, here the letter a will always mean the coefficient on the square of the variable, and b will be the coefficient on the variable, and c will be the constant term.
		Quadratic equations are harder to solve than linear equations, because once you have them in standard form it is hard to simplify them any further, and in this form there are still two occurrences of the variable, so it's hard to see what we can do to get the variable alone.

		Recall that an extraneous solution is one that is a solution to an equation after doing something like raising both sides of an equation by an even power, but is not a solution to the original problem.
		Even though not all of the quadratic in form equations can cause extraneous solutions, it is better to be safe than sorry and just check them all.
		Note how the original equation has the exact same expression in the two ()'s and that the first () is squared and the 2nd () is to the one power.

		There are three important cases of quadratics depending on where the graph crosses the x-axis (these points are called roots or zeros of the equation).
		In general, there are two big things we want to do with a quadratic equation: solve it for all possible values of x, or graph the equation.
		There are three main methods of solving quadratics: Guessing the solutions (also known as the double parentheses method), completing the square, and using the quadratic formula.

	Mr. G's Quadratic Equations
		When solving a quadratic equation by factoring we start by putting "everything on one side of the equation and zero on the other".
		When you have an equation to solve such as 3x+5=0 the solution can be found by putting the constant term over the variable's coefficient and using the opposite sign that's between them.
		Solving a quadratic equation by completing the square is based on factoring and the square root property.

	The roots of a Quadratic Equation
		For b = -2, the parabola is tangent to the x-axis and so the original equation has one real and positive root at the point of tangency.
		Remember the roots (sometimes also called "zeros") of a quadratic equation, f(x) =0, are the values of x for which the equation is satisfied.
		Note that this is the quadratic formula and this formula is used to find the roots of a quadratic equation.
