To find the zeros, set y = 0

Now try to isolate the (x-4)^2 term (move 10 to right side, divide by -5)

Next take square root of both sides (this cancels the square on (x-4))


For interpretation, x = price, y = profit
We are solving for price where profit = 0.
Answer:

Step-by-step explanation:
Given
List of Options
Required
Which of the options has a degree of 2
The general format of a polynomial is

<em>Where n represents the degree </em>
In this case;
n = 2
Substitute 2 for n in expression above;





Comparing this format to the list of given options; the option with the same format is: 
Where
;
and 
<em>Hence, the polynomial with a degree of 2 is </em>
Answer:
<em>The square root of 36/196 is </em><em>3</em><em>/</em><em>7</em><em>.</em>
<em>The </em><em>square</em><em> root</em><em> of</em><em> </em><em>3</em><em>6</em><em>/</em><em>1</em><em>6</em><em>9</em><em> </em><em> </em><em>is </em><em> </em><em>6</em><em>/</em><em>1</em><em>3</em><em>.</em>
The answer is D
