Given the 3 points you entered of (17,17), (12,7), and (12,24):

Calculate the quadratic equation formed by those 3 points

##### Use Cramers Rule

b = x-coordinate of 17

a = x-coordinate squared

17^{2} = 289

c is always equal to 1

d = our y-coordinate of 17

##### Determine values (e, f, g, h)

f = x-coordinate of 12

e = x-coordinate squared

12^{2} = 144

g is always equal to 1

h = our y-coordinate of 7

##### Determine values (i, j, k, l)

j = x-coordinate of 12

i = x-coordinate squared

12^{2} = 144

k is always equal to 1

l = our y-coordinate of 24
