There is a triangle with points A(2,-3), B(6,5), and C (0,5). The triangle is inscribed in a circle. (I don't know if the circle is important because a previous step told me to do that.) The area of the triangle is 21. 1 units^2 through Herons formula. I'll provide the slopes just in case. AB: square root (80) BC: 6 CA: Square root (68). The question is find the coefficients a, b, and c in the equation y=ax^2+bx+c so that the graph of the equation contains points A, B, C. I think that I somehow have to use matrices to solve. If anyone has any idea on how to solve it. Please, don't feel shy to share. I'm desperate.
