2x^2 -8x+5=0
Rewrite this quadratic into vertex form and then give the vertex:

Step-by-step explanation:

Starting with

, first add 5 to both sides to get:

2

x

=

5

Divide both sides by 2 to get:

x

=

5

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
