Use the information provided to write the vertex form equation of each parabola.
a)y + 60x + 294 = 3x^2
b)−(y+1) = (x−4)^2

a. y = 3x^2 60x  294.General or STD Form.
h = b/2a = 60 / 6 = 10.
k = 3(10)^2  60*10  294 = 6.
y = a(xh)^2 + k,
y = 3(x+10)^2 + 6. Vertex Form.
b. (y+1) = (x4)^2,
y1 = x^2  8x + 16,
y = x^2  8x + 17,
y = x^2 + 8x  17,
h = b/2a = 8 / 2 = 4.
k = (4)^2 +8*4  17 = 1.
y = (x4)^2  1.
