Given the 3 points you entered of (16,15), (12,21), and (1,15), calculate the quadratic equation formed by those 3 points

b represents our x-coordinate of 16

a is our x-coordinate squared → 16

c is always equal to 1

d represents our y-coordinate of 15

256a + 16b + c = 15

f represents our x-coordinate of 12

e is our x-coordinate squared → 12

g is always equal to 1

h represents our y-coordinate of 21

144a + 12b + c = 21

j represents our x-coordinate of 1

i is our x-coordinate squared → 1

k is always equal to 1

l represents our y-coordinate of 15

a + b + c = 15
