Expand the brackets by multiplying everything in the brackets by -0.25.
-x x -0.25 = 0.25x
-12 x -0.25 = 3
0.25x + 3 = 2
-3 from both sides.
0.25x = -1
Divide both by 0.25
x = -4

Step-by-step explanation:
The vertex form of the equation for a parabola is given by

where (h, k) are the coordinates of the parabola's vertex. Since the vertex is at (1, -6), we can write the equation as

Also, since the parabola passes through (4, -7), we can use this to find the value for a:

or

Therefore, the equation of the parabola is
