i have an task:
find a,b and c in the quadratic equation f(x) = ax^(2) +bx +c
which pass through the points : P(1,6), Q(-1,8) and R(2,11). Use the matrices
I started with:
a(1)^2 + b(1) + c = 6
a(-1)^2 +b(-1) + c = 8
a(2)^2+b*2 + c = 11
1 1 1 6
1 -1 1 8
4 2 1 11
does anyone know how to solve this further?
