Integration to find a bound area

**needmathshelp** · August 5th 2007, 01:37 PM

Can anyone please help me find the area bound by y1(x) = x ^3 - 2x^2- 5x +3 and y2(x) = x^2- 2x -3 using the integration techniques.

If you set the two equal and solve for x you find 3 intersection points to determine your limits of integration.

They are x= -1.529, 1.167, 3.361

You get $\int_{-1.529}^{1.167}[x^{3}-3x^{2}-3x+6]dx+\int_{1.167}^{3.361}[-x^{3}+3x^{2}+3x-6]dx$
