Given the 3 points you entered of (1,13), (13,20), and (25,23), calculate the quadratic equation formed by those 3 points

b represents our x-coordinate of 1

a is our x-coordinate squared → 1

c is always equal to 1

d represents our y-coordinate of 13

a + b + c = 13

f represents our x-coordinate of 13

e is our x-coordinate squared → 13

g is always equal to 1

h represents our y-coordinate of 20

169a + 13b + c = 20

j represents our x-coordinate of 25

i is our x-coordinate squared → 25

k is always equal to 1

l represents our y-coordinate of 23

625a + 25b + c = 23
