Express each equation in standard form and give the coordinates of the centre, or, in the case of a parabola, the
vertex.
17. 9x2 + y + 36x = 9
18. ?+? - 2x + 4y = 5
19. 9x? - 4y - 8y + 32 = 0
20. 3x² + 12x - 4y - 12 = 0

Plz show ALL STEPS and plz HURRY

G(x)=x2-16xb=-16, so =16 = 649(x) = (x2 - 16x + 64) - 649(x) = (x - 1)2-
