Answer:
<em>d</em> =
or 8.60
Step-by-step explanation:
(5, 8) (-2, 3)
Let 5 = 
8 = 
-2 = 
3 = 
Plug in the values into the equation to get the distance:
<em>d = </em>
<em />
<em>d </em>= 
<em>d = </em>
<em>d</em> = 
<em>d = </em>
or 8.60

A quadratic equation is one in which the highest exponent of x is 2.

is quadratic; the highest exponent is 2.
x³-3x²+1=0 is NOT quadratic. The highest exponent of x is 3, not 2.
5x-7=0 is NOT quadratic. The highest exponent of x is 1, not 2.
x²+3x-5=0 is quadratic; the highest exponent of x is 2.
x-5=9x+7 is NOT quadratic. The highest exponent of x is 1, not 2.
x²-x=3x+7 is quadratic; the highest exponent of x is 2.
