Asked by Kane
find the constants a, b and c such that or all values of x,
3x^2 - 5x + 1 = a(x+b)^2 +c
also whats the coordinate of the minimum point??
thanks for the help
3x^2 - 5x + 1 = a(x+b)^2 +c

Y = 3x^2 _ 5x + 1.
Vertex Form: y = a(x - h)^2 + k,
a = 3 = coefficient of x^2.
h = Xv = -b / 2a = 5/6 = 0.833.
Substitute 5/6 for x in the given Eq:
K = Yv=3*(5/6)^2 - 5*5/6 + 1 = -1.083.
Vertex Form: Y = 3(x - 5/6)^2 - 1.083.
V(h , k)=V(0.833 , -1.083) = Lowest
point.
