Given the 3 points you entered of (), (), and (), calculate the quadratic equation formed by those 3 points Practice Problem

Enter 3 points below:

<-- Point 1

<-- Point 2

<-- Point 3

Given the 3 points you entered of (21,3), (7,17), and (17,1):

Calculate the quadratic equation formed by those 3 points

Use Cramers Rule

b = x-coordinate of 21

a = x-coordinate squared
21² = 441

c is always equal to 1

d = our y-coordinate of 3

Determine values (e, f, g, h)

f = x-coordinate of 7

e = x-coordinate squared
7² = 49

g is always equal to 1

h = our y-coordinate of 17

Determine values (i, j, k, l)

j = x-coordinate of 17

i = x-coordinate squared
17² = 289

k is always equal to 1

l = our y-coordinate of 1
