The
vertex form of a quadratic function <span>is given by
</span>

where (h,k) is the vertex of parabola. In some literatures, the
standard form of the quadratic equation is written as
Therefore, in order to avoid the confusion, the first equation is taken as a vertex form. When the standard form is converted into the vertex form, the process is called
completing the square.
Answer:
0.548 = 5.48 * 
Step-by-step explanation:
in standard form you have to have most of the numbers after the decimal and only 1 behind it, in this case 5 is behind, and the rest infront.
9.1-12 inches is the correct answer
