Both A and B will be answers to the solution.
Since you already have the equation set and equal to 0, you can find the roots by first getting your a, b, and c values for the quadratic equation.
a = 1 (number attached to the x^2)
b = -3 (number attached to the x)
c = 5 (number not attached to a variable)
Then we can use these values in the quadratic equation.


Answer:
5,280 * 8 = 42,240
42,240 feet
42,240 * 12 = 506,880
506,880 inches
Step-by-step explanation:
Implicit differentiation
chain rule is important here
I'll show the steps partially




now evaluate for (-2,2)
x=-2 and y=2



that's it, simplest form
