Which equation is y=-3x2 – 12x – 2 rewritten in vertex form?
y=-3(x + 2)2 + 10
y=-3(x - 2)2 + 10
y=-3(x + 2)2 – 14
y=-3(x - 2)2 - 2

the answer is the first one

Step-by-step explanation:

the easiest way is to look at the constant. negitive three multiplies with 2 to get -6. Then it is multiplied with 2 again to get -12. Then add 10 to get -2.
