Any ideas?

Answer 2

OK this question has a few steps
1. take each point at a time, and plug them into y = ax2 + bx + c, so that you get 3 equations (this is ur system of equations)

2. Plug the three equations into a 3x4 matrix

3. Use Gauss-Jordan, or any other method u know, to solve the matrix.
That is, get:
Where a,b and c are the three constants of the quadratic equation
