(-2, 18)

(2, 2)

(2, 6)

Answer 1

Use the formula \[\frac{ -b }{ 2a }\]

If your still confused a equals the first term in the equation you provided and b is the second and so on. Then after you get an answer from the formula I provided insert that answer for X in the equation that you provided.

Answer 2
