This is a second degree equation where one variable out of all contains the exponent of 2. ax2+bx+c= 0 is a quadratic equation where x is not equal to zero. 3. Radical equations These are equations whose maximum exponent on the variable is ½ and have more than one term. Here the...
Normally a quadratic equation will graph out into a parabola. The standard form is f(x)=a(x-h)2+k
As shown below, the graph of a quadratic equation is a parabola. The graph of a quadratic equation forms a parabola. The technique of graphing as it is practiced today is based on the work of René Descartes. (Image credit: Robert Coolman) An ancient quadratic: The golden ratio To ...
