Given the 3 points you entered of (8,12), (22,15), and (21,15), calculate the quadratic equation formed by those 3 points

b represents our x-coordinate of 8

a is our x-coordinate squared → 8

c is always equal to 1

d represents our y-coordinate of 12

64a + 8b + c = 12

f represents our x-coordinate of 22

e is our x-coordinate squared → 22

g is always equal to 1

h represents our y-coordinate of 15

484a + 22b + c = 15

j represents our x-coordinate of 21

i is our x-coordinate squared → 21

k is always equal to 1

l represents our y-coordinate of 15

441a + 21b + c = 15
