Use completing the square to rewrite the equation in one of the standard forms for a conic and identify the conic.
1) x2 + 12x - y + 30 = 0
x^2 + 12x = y - 30
x^2 + 12x + 36 = y - 30 + 36
(x + 6)^2 = y + 6
y = (x + 6)^2 - 6
This is of the form y = a(x - h)^2 + k, where (h, k) = (-6, -6) and a = 1
It represents a parabola with vertex at (-6, -6) and opening upwards.
