Homework Statement
The curve y = ax2 + bx + c passes through the points Q(x1,y1) R(x2,y2), S(x3,y3). Show that the coefficients a, b, and c are a solution of the system of linear equations whose augmented matrix is x12 + x1 + 1 = y1
x22 + x2 + 1 = y2 x32 + x3 + 1 = y3
Homework Equations
The Attempt at a Solution
I don't know where to start, I tried creating linear equations using the points Q, R, and S and the point slope formula. but it got messy. This is from Anton's 10th edition of Linear Algebra with applications pg. 10
