Answer:

Step-by-step explanation:
We begin with the equation 
In order to get x on the left side, we need to square root both sides. As we are taking the square root of each sides, one of the sides must have a ± added to it in order to make sure that both of the solutions are found.
± 
We can then simplify this
± 
And once more
± 
Which means that our solutions are

Answer:
A is (-3,0) and (1,0).
B is (-1, -2).
Step-by-step explanation:
To find the x-intercepts, look along the x-axis and where the line goes through it. Those two locations are your answer.
To find the vertex, you can find the axis of symmetry by taking its equation and putting it into the form of x = -b/2a or finding the lowest or highest point in the line. In this example, it is (-1, -2) as the lowest point, and there is not a highest point to find, since it is in a u-shape.
