Write the equation of the quadratic function which includes points A (-1, 10), B (2, 19), C (1,4)

Correct result:

a =  0
b =  0
c =  0

#### Solution:

System of equations are non-linear.
The equations have the following integer solutions:
a*(-1)^2+b(-1)+c=10
a*(2)^2+b(2)+c=19
a*(1)^2+b(1)+c=4

Number of solutions found: 1
##### a1=6, b1=-3, c1=1

Our linear equations calculator calculates it.
$f(x)=ax^2 = bx+c = 6x^2-3x+1$
