Answer:
x = ± 2i![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Step-by-step explanation:
note that
= i
x² = - 12 ( take square root of both sides )
x = ±
= ±
= ± 2i![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Simply the radical expression
![y = -2(x-5)^2 + 7](https://tex.z-dn.net/?f=%20y%20%3D%20-2%28x-5%29%5E2%20%2B%207)
That's vertex form for a parabola
and we read off vertex (p,q) as
Answer: Vertex (5,7)
The negative <em>a</em> tells us this is a downward opening parabola (upside down from the usual
. I remember CUP - Concave Up Positive; here <em>a </em>is negative so not a cup, instead concave <em>down.</em> The same rule applies to second derivatives in calculus so memorize it now and use it later.
