The Quadratic Equation calculator returns the real value roots of a second degree polynomial.
INSTRUCTIONS: Enter the following:
Quadratic Roots (x): The calculator returns the real value roots. These are the values of x where the graph of the equation crosses the x axis where y is equal to zero.
The Quadratic Equation computes the two solutions of a second order polynomial of the form:
aX²+bX+C = 0
Note, the algorithm in this equation precludes imaginary root (those including the square root of negative numbers). For a derivation of the quadratic formula, see the video:
