In this article, we’ll walk through the process of finding the area bounded by the parabolas ( y = x^2 ) and ( y = 4x - x^2 ). We’ll start by identifying their points of intersection, then set up the integral to compute the enclosed area—perfect for students and learners seeking clarity on this essential topic.", "---", "### Step 1: Find the Points of Intersection\nTo determine the region enclosed by two curves, we first locate where they intersect. This requires solving:\n[\nx^2 = 4x - x^2\n]\nBring all terms to one side:\n[\nx^2 - (4x - x^2) = 0 \quad \Rightarrow \quad 2x^2 - 4x = 0\n]\nFactor the expression:\n[\n2x(x - 2) = 0\n]\nThus, the solutions are:\n[\nx = 0 \quad \ ext{and} \quad x = 2\n]\nThese x-values correspond to the endpoints of the region.

For the curves ( y = x^2 ) and ( y = 4x - x^2 ), the enclosed area between ( x = 0 ) and ( x = 2 ) is exactly ( \frac{8}{3} ) square units.
