Find the area of the region enclosed by the curves y^2 - 5x=4 and x-y=2

[William DeMeo]

Do you have a specific question about this problem?

[Caitlin King]

I understand that you need to put in terms of y and then find where the two equations intersect to find the interval. Then you take the integral of the two equations and its x=y+2 subtracted by the other equation. But every time that I tried to calculate the area I was getting a negative number and I took the absolute value.

I did this one in lecture.  

Please provide more details about your attempted solution so I can help you.

What are the two functions?  Please tell me how you have written the expression y^2 - 5x = 4 as a function of y. That is, when you write it as x = f(y), what is f(y) in this case?  

Next, if you write down the expression you are using as your integrand, then I will tell you if/why it's wrong.
