y=x

^{2}-5x and y=3-x

^{2}

Answer:

So, using simultaneous equations I found the points of intersection (x = -0.5 and x = 3). The book agrees with me on that.

I then performed the following:

3-x

^{2}-(x

^{2}-5x)

= -2x

^{2}+5x+3

I then integrated that:

((-2/3)*x

^{3})+((5/2)*x

^{2})+3x

I then subtracted the result when I substitute -0.5 from the result I get when I substitute 3. The book claims the answer is 2.655 but, no matter how hard I try I keep getting (271/24)

Can anyone help me here please?

Thanks!
