Equation Generator

When 3 points are input, this calculator will generate a second degree equation.
If you are familiar with graphing algebraic equations, then you are familiar with the concepts of the horizontal X-Axis and the Vertical Y-Axis. (This system of graphing is known as Cartesian coordinates, named after the French mathematician René Descartes (1596-1650) who devised the system).

Point values are written inside parentheses, with the X value written first, then a comma and then the Y value. For example, the point X=11 Y=3 would be written (11, 3).

Let's suppose we have the points (4, 9) (3, 0) and (2, -7) we can generate an equation by inputting these numbers in the boxes below.

Click E N T E R and your answer should be:

X² + 2X -15

X1=     Y1=

X2=     Y2=

X3=     Y3=
